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).
This bit is enabled w hen the SYNC bit in the TRDMR register is set to 1 (TRD0 and TRD1 registers operate
synchronously).
