9.3.23
TDDR is a 16-bit register, used only in complementary PWM mode that specifies the TCNT_3
and TCNT_4 counter offset values. In complementary PWM mode, when the TCNT_3 and
TCNT_4 counters are cleared and then restarted, the TDDR register value is loaded into the
TCNT_3 counter and the count operation starts.
The initial value of TDDR is H'FFFF.
Initial value:
9.3.24
TCDR is a 16-bit register used only in complementary PWM mode. Set half the PWM carrier sync
value as the TCDR register value. This register is constantly compared with the TCNTS counter in
complementary PWM mode, and when a match occurs, the TCNTS counter switches direction
(decrement to increment).
The initial value of TCDR is H'FFFF.
Initial value:
