Read/Write
XXXX 007C
Can be written or read during configuration cycle, memory cycle when enabled (see
the PCINT Base Address Control Register on page 111), or an I/O cycle. This reg-
ister 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.

This bit on will make the target respond with a target abort sequence, provided all the
other conditions are set correctly in this register.
This bit on will invert the value of PCI PAR64, provided all the other conditions are set
correctly in this register.
This bit on will invert the value of PCI PAR, provided all the other conditions are set
correctly in this register.
This bit on will flow a PCI Serr#, provided all the other conditions are set correctly in
this register. Bit 8 of the PCINT Config Word 1 does not need to be set to cause this
condition.
This bit on will flow a PCI Perr#, provided all the other conditions are set correctly in
this register. Bit 6 of the PCINT Config Word 1 does not need to be set to cause this
condition.
These bits will determine which kind of cycle to count based on the transfer size for
counter 2. The defines are the same as bits 21-20.
