Timer Dead Time Data Register (TDDR)
The timer dead time data register (TDDR) is a 16-bit register, used only in complementary PWM
mode, that specifies the TCNT3 and TCNT4 counter offset values. In complementary PWM mode,
when the TCNT3 and TCNT4 counters are cleared and then restarted, the TDDR register value is
loaded into the TCNT3 counter and the count operation starts. The TDDR register is initialized to
H'FFFF by a power-on reset or in standby mode. Manual reset does not initialize TDDR.
Accessing the TDDR in 8-bit units is prohibited. Always access in 16-bit units.

Timer Period Data Register (TCDR)
The timer period data register (TCDR) is a 16-bit register used only in complementary PWM
mode. Set 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 TCDR register is initialized to H'FFFF by a reset or in standby mode. Manual reset does not
initialize TCDR. Accessing the TCDR in 8-bit units is prohibited. Always access in 16-bit units.
