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.
