25 IIRQ 1 R Idle Mode Interrupt Status Flag
This interrupt status flag indicates whether this module
is in idle state.

allow polling.
The interrupt can be masked by clearing IIEN, but
cannot be cleared by writing to this bit.
If IIRQ = 1 and IIEN = 1, an interrupt occurs.
0: This module is not in idle state.

4 TSWNO 1 R Transmit Serial Word Number
This status bit indicates the current word number.
This bit indicates which system word is required to be
