For F642/542N, Bit 2 ~ Bit 0 are unused. Set to “0” all the time.
For F641/541N, Bit 4 ~ Bit 0 are unused. Set to “0” all the time.
Individual interrupt is enabled by setting its associated control bit in the IOCF to "1".
Global interrupt is enabled by the ENI instruction and is disabled by the DISI
For F642/542N, Bit 5 ~ Bit 3 are unused. Set to “0” all the time.
For F641/541N, Bit 5 ~ Bit 3 are unused. Set to “0” all the time.
