interrupt request status bit)

0: Interrupt not requested

1: Interrupt requested
W= : Only writing 0 is effective. Writing 1 has no effect, the bit retains the value it had before writing.
Transmit/receive interrupt requests from SIO2 and SIO3 are described below.
[Setting the interrupt request status bit]
The interrupt request status bit is set in hardware, and cannot be set in software.
[Clearing the interrupt request status bit]
The interrupt request status bit is cleared by writing 0 in software.
Note: If the status bit is set in hardware at the same time it is cleared in software, the
former has priority so that the status bit is set.
When writing to the SIO Interrupt Request Status Register, be sure to write 0 for the bits to be
cleared and 1 for all other bits. Writing 1 in software does not affect any bit of this register, the bit
retains the value it had before writing.
