18.3.12 Timer Gate Control Register (TGCR)
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.

Description
Reserved
This bit is always read as 1. The write value should
always be 1.
Brushless DC Motor
This bit selects whether to make the functions of this
register (TGCR) effective or ineffective.
0: Ordinary output
1: Functions of this register are made effective
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
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
