This bit is enabled w hen the STCLK bit in the TRDFCR register is set to 1 (external clock input enabled).
Set the TCK2 to TCK0 bits and CKEG1 to CKEG0 bits in the TRDCR0 and TRDCR1 registers to the same values.
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).
