When the interrupt output INTB goes low, this register allows the source of the active interrupt to
be identified down to the block level. 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.
TXCPI:
The TXCPI bit is high when an interrupt request is active from the TXCP block. The TXCP
interrupt sources are enabled in the TXCP Interrupt Control/Status Register.
