Description

—

Reserved

This bit is always read as 1. The write value should

always be 1.

BDC

R/W

Brushless DC Motor

This bit selects whether to make the functions of this

0: Ordinary output

1: Functions of this register are made effective

R/W

Reverse Phase Output (N) Control

This bit selects whether the level output or the reset-

synchronized PWM/complementary PWM output while

the reverse pins (TIOC3D, TIOC4C, and TIOC4D) are

on-output.

0: Level output

1: Reset synchronized PWM/complementary PWM

output

R/W

Positive Phase Output (P) Control

This bit selects whether the level output or the reset-

synchronized PWM/complementary PWM output while

the positive pin (TIOC3B, TIOC4A, and TIOC4B) are on-

output.

0: Level output

1: Reset synchronized PWM/complementary PWM

output

R/W

External Feedback Signal Enable

This bit selects whether the switching of the output of the

positive/reverse phase is carried out automatically with

the MTU/channel 0 TGRA, TGRB, TGRC input capture

signals or by writing 0 or 1 to bits 2 to 0 in TGCR.

0: Output switching is carried out by external input (Input

sources are channel 0 TGRA, TGRB, TGRC input

capture signal)

1: Output switching is carried out by software (TGCR's

UF, VF, WF settings).

R/W

Output Phase Switch 2 to 0

These bits set the positive phase/negative phase output

phase on or off state. The setting of these bits is valid

only when the FB bit in this register is set to 1. In this

case, the setting of bits 2 to 0 is a substitute for external

input. See table 8.28.
