3. The TRDCR1 register is not used in reset synchronous PWM mode.
This setting is enabled w hen the STCLK bit in the TRDFCR register is set to 1 (external clock input enabled).
Bits CKEG1 to CKEG0 are enabled w hen bits TCK2 to TCK0 are set to 101b (TRDCLK input) and the STCLK bit in the
TRDFCR register is set to 1 (external clock input enabled).
