Can be written or read during configuration cycle, memory cycle when enabled (see
PCINT Base Address Control Register on page 111), or an I/O cycle. This register
is documented as Big Endian, but how data is presented on the PCI bus depends
on how the controls are set in the PCINT Endian Control Register.

The bits can be set to determine how many PCI cycles a register access will wait for
an internal cycle to complete for a read access. It can be programmed to wait for up to
seven cycles. A value of ‘0’ will not timeout this access with a retry.
Reserved
Setting this bit to ’1’ enables the values of PCINT Window Offsets for Base Addresses
3-6 so that it updated with a good get primitive or certain receive queue dequeues.
Setting this bit to ’1’ disables PCI retry signaling during a register or primitive access.
Setting this bit to ’1’ disables this PCI locking function when set to ’1’
This bit is for Crisco code use. When set to ’1’, it disables all responses to the PCI bus
in slave mode. In general, never turn this bit on. Bit 19 of the PCINT Base Address
Control Register must be set before this bit can be changed.
