Timer Gate Control Register (TGCR)

The timer gate control register (TGCR) is an 8-bit read/write register that controls the waveform

output necessary for brushless DC motor control in complementary PWM mode/reset-

synchronized PWM mode. The TGCR is initialized to H'80 by a power-on reset or in the standby

mode. Manual reset does not initialize TGCR. These register settings are ineffective for anything

other than complementary PWM mode/reset-synchronized PWM mode.

• Bit 7—Reserved: This bit always reads as 1. The write value should always be 1.
