PCIIR records the source of an interrupt.
When multiple interrupts occur, only the first source is registered.
When an interrupt is disabled, the source is registered in corresponding bit (set to 1) in this
register, however, no interrupt occurs.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Target Target-Abort Interrupt
Indicates that the PCIC has terminated a transaction
with a target-abort when the PCIC functions as a
target.
A target-abort is detected as an illegal byte enable
when the lower two bits (bits 1 and 0) of the address
and the byte enable do not match during an I/O
transfer (target).
0: Target-abort interrupt does not occur
[Clear condition]
Write 1 to this bit (write clear).
1: Target-abort interrupt occurs
[Set condition]
When a target-abort interrupt occurs.
