NOTES:
1.
2. When bits CMD1 to CMD0 are set to 00b (timer mode, PWM mode, or PWM3 mode), the setting of the PWM3 bit is
enabled.

RW
CMD1 RW
Combination mode selection bit
(1)
Set to 00b (timer mode, PWM mode, or
PWM3 mode) in the input capture function.
CMD0
Normal-phase output level selection
bit (in reset synchronous PWM mode
or complementary PWM mode)
This bit is disabled in the input capture
function.
Set bits CMD1 to CMD0 when both the TSTART0 and TSTART1 bits in the TRDSTR register are set to 0 (count stops).
OLS0 RW
RW
Counter-phase output level selection
bit (in reset synchronous PWM mode
or complementary PWM mode)
This bit is disabled in the input capture
function.
A/D trigger enable bit
(in complementary PWM mode)
This bit is disabled in the input capture
function.
RW
PWM3 RW
ADTRG
ADEG
A/D trigger edge selection bit
(in complementary PWM mode)
This bit is disabled in the input capture
function.
RW
PWM3 mode selection bit
(2)
Set this bit to 1 (other than PWM3 mode) in
the input capture function.
STCLK
External clock input selection bit 0 : External clock input disabled
1 : External clock input enabled
