• Manufacturer Part Number: p2125vps20
• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

To perform PWM 256/256 output when DDR = 1 and OE = 0, the corresponding pin should be set
to port output. The corresponding pin can be set as port output in single-chip mode (PW15 to
PW0) or when IOSE = 1 (PW15 to PW12) in SYSCR in extended mode with on-chip ROM.
Otherwise, it should be noted that an address bus is output to the corresponding pin.
DR data is output when the corresponding pin is used as port output. A value corresponding to
PWM 256/256 output is determined by the OE bit, so the value should have been set to DR
beforehand.
