 * Description:  This register's value is a bit vector that guards      *
 * access to local registers within the II as well as to external       *
 * Crosstalk widgets. Each bit in the register corresponds to a         *
 * particular region in the system; a region consists of one, two or    *
 * four nodes (depending on the value of the REGION_SIZE field in the   *
 * LB_REV_ID register, which is documented in Section 8.3.1.1). The     *
 * protection provided by this register applies to PIO read             *
 * operations as well as PIO write operations. The II will perform a    *
 * PIO read or write request only if the bit for the requestor's        *
 * region is set; otherwise, the II will not perform the requested      *
 * operation and will return an error response. When a PIO read or      *
 * write request targets an external Crosstalk widget, then not only    *
 * must the bit for the requestor's region be set in the ILAPR, but     *
 * also the target widget's bit in the IOWA register must be set in     *
 * order for the II to perform the requested operation; otherwise,      *
 * the II will return an error response. Hence, the protection          *
 * provided by the IOWA register supplements the protection provided    *
 * by the ILAPR for requests that target external Crosstalk widgets.    *
 * This register itself can be accessed only by the nodes whose         *
 * region ID bits are enabled in this same register. It can also be     *
 * accessed through the IAlias space by the local processors.           *
 * The reset value of this register allows access by all nodes.         *
 *                                                                      *

 * Description:  There are 9 instances of this register, one per        *
 * actual widget in this implementation of Bedrock and Crossbow.        *
 * Note: Crossbow only has ports for Widgets 8 through F, widget 0      *
 * refers to Crossbow's internal space.                                 *
 * This register contains the state elements per widget that are        *
 * necessary to manage the PIO flow control on Crosstalk and on the     *
 * Router Network. See the PIO Flow Control chapter for a complete      *
 * description of this register                                         *
 * The SPUR_WR bit requires some explanation. When this register is     *
 * written, the new value of the C field is captured in an internal     *
 * register so the hardware can remember what the programmer wrote      *
 * into the credit counter. The SPUR_WR bit sets whenever the C field   *
 * increments above this stored value, which indicates that there       *
 * have been more responses received than requests sent. The SPUR_WR    *
 * bit cannot be cleared until a value is written to the IPRBx          *
 * register; the write will correct the C field and capture its new     *
 * value in the internal register. Even if IECLR[E_PRB_x] is set, the   *
 * SPUR_WR bit will persist if IPRBx hasn't yet been written.           *

 * Description:  This register specifies the timeout value to use for   *
 * monitoring Crosstalk tail flits coming into the Bedrock in the       *
 * TAIL_TO field. An internal counter associated with this register     *
 * is incremented every 128 II internal clocks (7 bits). The counter    *
 * starts counting anytime a header micropacket is received and stops   *
 * counting (and resets to zero) any time a micropacket with a Tail     *
 * bit is received. Once the counter reaches the threshold value        *
 * programmed in this register, it generates an interrupt to the        *
 * processor that is programmed into the IIDSR. The counter saturates   *
 * (does not roll over) at its maximum value, so it cannot cause        *
 * another interrupt until after it is cleared.                         *
 * The register also contains the Read Response Timeout values. The     *
 * Prescalar is 23 bits, and counts II clocks. An internal counter      *
 * increments on every II clock and when it reaches the value in the    *
 * Prescalar field, all IPRTE registers with their valid bits set       *
 * have their Read Response timers bumped. Whenever any of them match   *
 * the value in the RRSP_TO field, a Read Response Timeout has          *
 * occurred, and error handling occurs as described in the Error        *

 * A write to this register causes an entry from the table of           *
 * outstanding PIO Read Requests to be freed and returned to the        *
 * stack of free entries. This register is used in handling the         *
 * timeout errors that result in a PIO Reply never returning from       *
 * Crosstalk.                                                           *
 * Note that this register does not affect the contents of the IPRTE    *
 * registers. The Valid bits in those registers have to be              *

 *  The Bedrock DEBUG unit provides a 3-bit selection signal to the     *
 * II unit, thus allowing a choice of one set of debug signal outputs   *
 * from a menu of 8 options. Each option is limited to 32 bits in       *
 * size. There are more signals of interest than can be accommodated    *
 * in this 8*32 framework, so the IDBSS register has been defined to    *
 * extend the range of choices available. For each menu option          *
 * available to the DEBUG unit, the II provides a "submenu" of          *
 * several options. The value of the SUBMENU field in the IDBSS         *
 * register selects the desired submenu. Hence, the particular debug    *
 * signals provided by the II are determined by the 3-bit selection     *
 * signal from the DEBUG unit and the value of the SUBMENU field        *
 * within the IDBSS register. For a detailed description of the         *

 * While the transfer is in progress, hardware will decrement the       *
 * length field with each successful block that is copied. Once the     *
 * transfer completes, hardware will clear the Busy bit. The length     *
 * field will also contain the number of cache lines left to be         *
