When set to 1, inhibits ITARG interrupt requests
5 INHISY 0 R/W ISY Interrupt Mask
When set to 1, inhibits ISY interrupt requests
4 INHIERR 0 R/W IERR Interrupt Mask
When set to 1, inhibits IERR interrupt requests
3 INHIBUF 0 R/W IBUF Interrupt Mask

1 PREINH
REQDM
0 R/W Inhibits setting of the DMA-transfer-request interrupt
source flag for the output data stream.
When this bit is set to 1, the DMA-transfer-request
interrupt source is not retained.
0 PREINH
IREADY
0 R/W Inhibits setting of the IREADY interrupt flag.
When this bit is set to 1, the IREADY interrupt source
not retained.
