PWDPR is initialized to H'00 by a reset and in hardware standby mode.
9.2.4
Each PWOER is an 8-bit readable/writable register that switches between PWM output and port
output. Bits OE15 to OE0 correspond to outputs PW15 to PW0. To set a pin in the output state, a
setting in the port direction register is also necessary. Bits P17DDR to P10DDR correspond to
outputs PW7 to PW0, and bits P27DDR to P20DDR correspond to outputs PW15 to PW8.
PWOER is initialized to H'00 by a reset and in hardware standby mode.
