Access PCD_STAT
Bit PCD_ Description
D0-3 STAT The state of user-definable STAT input signals as last
sampled by the RXT clock signal.
D4-7 STAT_INT Interrupt bits for the status bits. If the following conditions
are both true, then the corresponding bit of these four can
be asserted to cause a PCI Bus interrupt:
The device interrupt is enabled using the
RMT_EN_INTR bit in the PCI Interrupt and Remote
Xilinx Configuration register.
The corresponding bit is asserted in the command
register (one of bits 4–7, named STAT_INT_EN).
The PCI Bus interrupt is then caused when the
corresponding STAT signal is asserted according to the
polarity specified in the stat polarity register. To reset the
interrupt, disable and re-enable the appropriate
STAT_INT_EN bit in the command register.
