1.2.18Time Division Multiplexing (TDM) Interface

All of the TDM signals are multiplexed on the MPP pins (see Section 4, Pin Multiplexing, on page 51).

The TDM signals are powered on VDDO or on VDD_GE_B, based on the pin

Note multiplexing option (see Section 4, Pin Multiplexing, on page 51).

			VDD_GE_B
TDM_DTX	O	CMOS	VDDO/	PCM Audio Output Data (for playback)
			VDD_GE_B
TDM_SPI_CS[1:0]	O	CMOS	VDDO/	Active low SPI chip selects driven by the host to the codec for
			VDD_GE_B	register access. Always asserted for eight SCLK cycles at a time.
				Only Byte-by-Byte mode codec register read/write is supported.
TDM_SPI_SCK	O	CMOS	VDDO/	Serial SPI clock from the host to the codec for register access.
			VDD_GE_B	This is an RTO (return to one) clock. It toggles for eight cycles at
				a time (for 1 byte transfer) during codec register access, then it
				returns to high.
				The host drives write data on TDM_SPI_MOSI on the negative
				edge of TDM_SPI_SCK, and captures read data from the codec
				on the positive edge of TDM_SPI_SCK.
