• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

(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.

clock of the internal oscillator is divided and supplied as the count clock. If the count clock
is the internal oscillation clock, the operation of 8-bit timer H1 is not guaranteed (except
