The SERRI bit remains valid when interrupts are disabled and may be polled to detect PCI
system error events.
PERRI:
The parity error interrupt status bit (PERRI) reports PCI parity error interrupts to the PCI host.
PERRI is set high when data parity errors are detected by the FREEDM-8 while acting as a
master, and when parity errors are reported to the FREEDM-8 by a target via the PERRB
input. The PERRI bit remains valid when interrupts are disabled and may be polled to detect
PCI parity error events.
RFCSEI:
The receive frame check sequence error interrupt status bit (RFCSEI) reports receive FCS
error interrupts to the PCI host. RFCSEI is set high, when a mismatch between the received
FCS code and the computed CRC residue is detected. RFCSEI remains valid when
interrupts are disabled and may be polled to detect receive FCS error events.
RABRTI:
The receive abort interrupt status bit (RABRTI) reports receive HDLC abort interrupts to the
PCI host. RABRTI is set high upon receipt of an abort code (at least 7 contiguous 1's).
RABRTI remains valid when interrupts are disabled and may be polled to detect receive abort
events.
RPFEI:
The receive packet format error interrupt status bit (RPFEI) reports receive packet format
error interrupts to the PCI host. RPFEI is set high upon receipt of a packet that is longer than
the maximum programmed length, of a packet that is shorter than 32 bits (CRC-CCITT) or 48
bits (CRC-32), or of a packet that is not octet aligned. RPFEI remains valid when interrupts
are disabled and may be polled to detect receive packet format error events.
RFOVRI:
The receive FIFO overrun error interrupt status bit (RFOVRI) reports receive FIFO overrun
error interrupts to the PCI host. RFOVRI is set high on attempts to write data into the logical
FIFO of a channel when it is already full. RFOVRI remains valid when interrupts are disabled
and may be polled to detect receive FIFO overrun events.
RPQSFI:
The receive packet descriptor small buffer free queue cache read interrupt status bit
(RPQSFI) reports receive packet descriptor small free queue cache read interrupts to the PCI
host. RPQSFI is set high when the programmable number of RPDR blocks is read from the
RPDR Small Buffer Free Queue. RPQSFI remains valid when interrupts are disabled and
may be polled to detect RPDR small buffer free queue cache read events.
