This register provides interrupt enables for various events detected or initiated by
the FREEDM-84A672.
RFCSEE:
The receive frame check sequence error interrupt enable bit (RFCSEE)
enables receive FCS error interrupts to the microprocessor. 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 INTB 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 microprocessor. 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 INTB 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.
