(5) Port mode register 0 (PM0)
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
latches of P01 and P06 to 0.
When using the P00/TI000, P01/TO00/TI010, P05/TI001/SSI11, and P06/TO01/TI011 pins for timer input, set
PM00, PM01, PM05, and PM06 to 1. At this time, the output latches of P00, P01, P05, 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.
