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 when IOSE = 1 and CS256E = 0 in
SYSCR in single-chip mode or in extended mode with on-chip ROM enabled. 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 OS bit, so the value should be set to DR beforehand.

Description
Output Select 7 to 0
These bits select the PWM output phase. Bits OS7 to
OS0 correspond to outputs PW7 to PW0.
0: PWM direct output (PWDR value corresponds to high
width of output)
1: PWM inverted output (PWDR value corresponds to
low width of output)
Description
Output Enable 7 to 0
These bits, together with P1DDR, specify the P1n/PWn
pin state. Bits OE7 to OE0 correspond to outputs PW7
to PW0.
P1nDDR OEn: Pin state
0x: Port input
10: Port output or PWM 256/256 output
11: PWM output (0 to 255/256 output)
