(5) Port mode register 0 (PM0)
(6) Port mode register 3 (PM3)
190
This register sets port 0 input/output in 1-bit units.
When using the P01/TO00/TI010 and P06/TO01/TI011 pins for timer output, set PM01 and PM06 and the output
latch of P01 and P06 to 0.
When using the P01/TO00/TI010 and P06/TO01/TI011 pins for timer input, set PM01 and PM06 to 1. At this time,
the output latch of P01 and P06 may be 0 or 1.
PM0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM0 to FFH.
This register sets port 3 input/output in 1-bit units.
When using the P32/TO02/TI012/INTP3 pin for timer output, set PM32 and the output latch of P32 to 0.
When using the P31/TI002/INTP2 and P32/TI012/TO02/INTP3 pins for timer input, set PM31 and PM32 to 1. At
this time, the output latch of P31 and P32 may be 0 or 1.
PM3 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM3 to FFH.
