SERRE: 
The system error interrupt enable bit (SERRE) enables PCI system error 
interrupts to the PCI host.  When SERRE is set high, any address parity error, 
data parity error on Special Cycle commands, reception of a master abort or 
detection of a target abort will cause an interrupt to be generated on the 
PCIINTB output.  Interrupts are masked when SERRE is set low.  However, 
the SERRI bit remains valid when interrupts are disabled and may be polled 
to detect PCI system error events. 
PERRE: 
The parity error interrupt enable bit (PERRE) enables PCI parity error 
interrupts to the PCI host.  When PERRE is set high, data parity errors 
detected by the FREEDM-32P672 or parity errors reported by a target will 
cause an interrupt to be generated on the PCIINTB output.  Interrupts are 
masked when PERRE is set low.  However, the PERRI bit remains valid when 
interrupts are disabled and may be polled to detect PCI parity error events. 
RFCSEE: 
The receive frame check sequence error interrupt enable bit (RFCSEE) 
enables receive FCS error interrupts to the PCI host.  When RFCSEE is set 
high, a mismatch between the received FCS code and the computed CRC 
residue will cause an interrupt to be generated on the PCIINTB output.  
Interrupts are masked when RFCSEE is set low.  However, the RFCSEI bit 
remains valid when interrupts are disabled and may be polled to detect 
receive FCS error events. 
RABRTE: 
The receive abort interrupt enable bit (RABRTE) enables receive HDLC abort 
interrupts to the PCI host.  When RABRTE is set high, receipt of an abort 
code (at least 7 contiguous 1's) will cause an interrupt to be generated on the 
PCIINTB output.  Interrupts are masked when RABRTE is set low.  However, 
the RABRTI bit remains valid when interrupts are disabled and may be polled 
to detect receive abort events. 
RPFEE: 
The receive packet format error interrupt enable bit (RPFEE) enables receive 
packet format error interrupts to the PCI host.  When RPFEE is set high, 
receipt of a packet that is longer than the maximum specified in the RHDL 
Maximum Packet Length register, 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 will 
cause an interrupt to be generated on the PCIINTB output.  Interrupts are 
masked when RPFEE is set low.  However, the RPFEI bit remains valid when
