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.
