(3) Port mode registers 1 and 3 (PM1, PM3)
296
These registers set port 1 and 3 input/output in 1-bit units.
PM1 and PM3 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
When using the P30/TI51/TOH1/INTP1 pin for timer input, set PM30 to 1. The output latches of P30 at this time
may be 0 or 1.
When using the P17/TO50/TI50 and P33/TO51/TI51/INTP4 pins for timer output, clear PM17 and PM33 and the
output latches of P17 and P33 to 0.
When using the P17/TO50/TI50 and P33/TO51/TI51/INTP4 pins for timer input, set PM17 and PM33 to 1. The
output latches of P17 and P33 at this time may be 0 or 1.
