■
When THR bit = “1”, M/S bit = “0”, PMADL bit = “0” and PMADR bit = “0”, input clocks and data of EXLRCK,
EXBCLK and EXSDTI pins are bypassed to LRCK, BCLK and SDTO pins, respectively.
When THR bit = “1”, M/S bit = “0” and PMADL bit = “1” or PMADR bit = “1”, input clocks of EXLRCK and EXBCLK
pins are bypassed to LRCK and BCLK pins, and ADC data is output from the SDTO pin.
