Figure 9.3 shows an example of the PWM output level setting procedure in buffer operation.
9.3.21
TGCR is an 8-bit readable/writable register that controls the waveform output necessary for
brushless DC motor control in reset-synchronized PWM mode/complementary PWM mode. These
register settings are ineffective for anything other than complementary PWM mode/reset-
synchronized PWM mode.
