(2) Port mode register 1 (PM1)
Cautions 1. When the internal oscillation clock is selected as the clock to be supplied to the CPU, the
Remarks 1. f
This register sets port 1 input/output in 1-bit units.
When using the P15/TOH0 and P16/TOH1/INTP5 pins for timer output, clear PM15 and PM16 and the output
latches of P15 and P16 to 0.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to FFH.
