Serial Control Port Clock (Input) - Serial clock for the control port interface.
Serial Control Data I/O (Input/Output) - Input/Output for I²C data. Output for SPI data.
Address Bit [0]/ Chip Select (Input) - Chip address bit in I²C Mode. Control signal used to select
the chip in SPI Mode.
Address Bit [1]/ SPI Data Input (Input) - Chip address bit in I²C Mode. Input for SPI data.
Reset (Input) - The device enters a low-power mode and all internal registers are reset to their
default settings when low.
Control Port Power (Input) - Determines the required signal level for the control port interface.
See
Frame Sync (Input) - Signals the start of a new TDM frame in the TDM digital interface format.
Digital Power (Input) - Positive power supply for the digital section.
Serial Port Interface Power (Input) - Determines the required signal level for the serial port inter-
faces. See
