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.
CRSII:
The CRSII bit is high when an interrupt request is active from the Clock
Recovery and SIPO block (CRSI-622). The CRSI interrupt sources are
enabled in the Clock Recovery Interrupt Control/Status Register.
CSPII:
The CSPII bit is high when an interrupt request is active from the Clock
Synthesis and PISO block (CSPI-622). The CSPII interrupt sources are
enabled in the Clock Synthesis Interrupt Control/Status Register.
