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 or when IOSE
= 1 and CS256E = 0 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 OS bit, so the value should have been set to DR
beforehand.
