These bits, together with the CNTL[7:0] bits, reflect the content in the internal 16-bit EXZ counter.
These bits, together with the CNTH[7:0] bits, reflect the content in the internal 16-bit EXZ counter.
In case of LOS, this bit determines the outputs on the REFA_OUT and REFB_OUT pins.
= 0: Output MCLK.
= 1: Output high level.
