78K0/Kx2-L
(6) Port mode register 0 (PM0)
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
This register sets port 0 input/output in 1-bit units.
When using the P01/TO00/TI010 pin for timer output, set PM01 and the output latches of P01 to 0.
When using the P00/TI000 (P00/TI000/INTP0 in the 78K0/KY2-L and 78K0/KA2-L) and P01/TI010/TO00 pins for
timer input, set PM00 and PM01 to 1. At this time, the output latches of P00 and P01 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.
