• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
When THR bit = “1”, M/S bit = “0” and PMADC 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 PMADC bit = “1” input clocks of EXLRCK and EXBCLK pins are bypassed to
LRCK and BCLK pins, and ADC data is output from SDTO pin.
