• Bit 6—Brushless DC Motor (BDC): Selects gate signal output/chopping output function for

brushless DC motor control.

Bit 6: BDC

Description

Ordinary output (initial value)

Gate signal/chopping output for brushless DC motor

• Bit 5—Reverse Phase Output (N): Selects whether to output gate signals directly to the reverse

phase pin (TIOC3D, TIOC4C, and TIOC4D) output, or to output by chopping the gate signal

and the complementary PWM/reset-synchronized PWM output.

Bit 5: N

Description

Output gate signals directly to reverse phase pin output (initial value)

Output chopped gate signal and complementary PWM /reset-

synchronized PWM output to reverse phase pin output

• Bit 4—Positive Phase Output (P): Selects whether to output gate signals directly to the positive

phase pin (TIOC3B, TIOC4A, and TIOC4B) output, or to output by chopping the gate signal

and the complementary PWM/reset-synchronized PWM output.

Bit 4: P

Description

Output gate signals directly to positive phase pin output (initial value)

Output chopped gate signal and complementary PWM /reset-

synchronized PWM output to positive phase pin output

• Bit 3—Feedback Input (FB): Selects whether to use external input or register input for the

feedback input to generate gate signals.

Bit 3: FB

Description

Feedback input is external input (initial value)

(Input sources are channel 0 TGRA, TGRB, TGRC input capture signals)

Feedback input is register input (TGCR’s UF, VF, WF settings)
