Timer Output Control Register (TOCR)

The timer output control register (TOCR) enables/disables PWM synchronized toggle output in

complementary PWM mode and reset sync PWM mode, and controls output level inversion of

PWM output. The TOCR is initialized to H'00 by a power-on reset or in the standby mode.

Manual reset does not initialize TOCR. These register settings are ineffective for anything other

than complementary PWM mode/reset-synchronized PWM mode.

• Bits 7, 5–2—Reserved: These bits always read as 1. The write value should always be 1.

• Bit 6—PWM Synchronous Output Enable (PSYE): Selects the enable/disable of toggle output

synchronized with the PWM period.

• Bit 1—Output Level Select N (OLSN): Selects the reverse phase output level of the

complementary PWM mode or reset-synchronized PWM mode.

Note: * The reverse phase waveform initial output value changes to active level after elapse of the

dead time after count start.

• Bit 0—Output Level Select P (OLSP): Selects the positive phase output level of the

complementary PWM mode or reset-synchronized PWM mode.
