PCICR is a 32-bit register which specifies the operation of the PCIC.
The register is write protected; only writes in which the upper eight bits (that is, bits 31 to 24)
have the value H'A5 are performed. All other writes are ignored.

Description
Reserved
Set these bits to H'A5 only when writing to bits 11 to
8, 6, and 3 to 0.
These bits are always read as 0.
Reserved
These bits are always read as 0. The write value
should always be 0.
PCI Pre-Fetch Command Setting
This bit is valid only when the PFE bit is 1.
0: Always 8-byte pre-fetching
1: Always 32-byte pre-fetching
PCI TRDY Control Enable
In a target access, negate the TRDY, within 5 cycles
before disconnection.
0: Disabled
1: Enabled
