• Bit 0—PWM Mode 3 (T3PWM): Selects whether channel 3 operates in input capture/output
compare mode or PWM mode.
Bit 0: T3PWM
0
1
Description
Channel 3 operates in input capture/output compare mode
Channel 3 operates in PWM mode
(Initial value)
When bit T3PWM is set to 1 to select PWM mode, pins TIO3A to TIO3C become PWM
output pins, general register 3D (GR3D) functions as a cycle register, and general registers 3A
to 3C (GR3A to GR3C) function as duty registers. Settings in the timer I/O control registers
(TIOR3A, TIOR3B) are invalid, and general registers 3A to 3D (GR3A to GR3D) can be
written to. Do not use the TIO3D pin as a timer output.
11.2.10 PWM Mode Register (PMDR)
The PWM mode register (PMDR) is an 8-bit register. The ATU-II has one PMDR register.

PMDR is an 8-bit readable/writable register that selects whether channel 6 PWM output is set to
on-duty/off-duty, or to non-complementary PWM mode/complementary PWM mode.
PMDR is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
• Bit 7—Duty Selection Register D (DTSELD): Selects whether channel 6D TO6D output
PWM is set to on-duty or to off-duty.
Bit 7: DTSELD

Description
TO6D PWM output is on-duty
TO6D PWM output is off-duty
