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