Default: 0x0000

Bit Name Function
4 RDSPSXMIT
0 = Do not interrupt (default).
1 = Interrupt when a RDS PS Group has been transmitted. The interrupt occurs
when a PS group begins transmission.
3 RDSCBUFXMIT
0 = Do not interrupt (default).
1 = Interrupt when a RDS Group has been transmitted from the Circular Buffer.
The interrupt occurs when a group is fetched from the buffer.
2 RDSFIFOXMIT
0 = Do not interrupt (default).
1 = Interrupt when a RDS Group has been transmitted from the FIFO Buffer. The
interrupt occurs when a group is fetched from the buffer.
1 RDSCBUFWRAP
0 = Do not interrupt (default).
1 = Interrupt when the RDS Group Circular Buffer has wrapped. The interrupt
occurs when the last group is fetched from the buffer.
0 RDSFIFOMT
0 = Do not interrupt (default).
1 = Interrupt when the RDS Group FIFO Buffer is empty. The interrupt occurs
when the last group is fetched from the FIFO.
