This register provides interrupt enables for various events detected or initiated by the FREEDM.
Note
This register is not byte addressable. Writing to this register modifies all the bits in the register.
Byte selection using byte enable signals (CBEB[3:0]) are not implemented. However, when all
four byte enables are negated, no access is made to this register.
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.
