This register allows the source of an active interrupt to be identified down to the
block level within a given channel. Further register accesses are required for the
block in question to determine the cause of an active interrupt and to
acknowledge the interrupt source.
RSOPI:
The RSOPI bit is high when an interrupt request is active from the RSOP
block. The RSOP interrupt sources are enabled in the RSOP Control/Interrupt
Enable Register.
RLOPI:
The RLOPI bit is high when an interrupt request is active from the RLOP
block. The RLOP interrupt sources are enabled in the RLOP Interrupt
Enable/Status Register.
RPOPI:
The RPOPI bit is high when an interrupt request is active from the RPOP
block. The RPOP interrupt sources are enabled in the RPOP Interrupt Enable
Register.
RXCPI:
The RXCPI bit is high when an interrupt request is active from the RXCP
block. The RXCP interrupt sources are enabled in the RXCP Interrupt
Enable/Status Register.
