AD0 / CS
Digital Power (Input) - Digital core power supply. Typically +3.3 V or +5.0 V.
Logic Power (Input) - Input/Output power supply. Typically +3.3 V or +5.0 V.
Ground (Input) - Ground for I/O and core logic.
Reset (Input) - When RST is low, the CS8406 enters a low power mode and all internal states are reset.
On initial power up, RST must be held low until the power supply is stable, and all input clocks are stable
in frequency and phase. This is particularly true in Hardware Mode with multiple CS8406 devices, where
synchronization between devices is important.
Hardware/Software Control Mode Select (Input) -Determines the method of controlling the operation
of the CS8406, and the method of accessing CS and U data. In Software Mode, device control and CS
and U data access is primarily through the control port, using a microcontroller. To select Software
Mode, this pin should be permanently tied to GND.
Differential Line Drivers (Output) - These pins transmit biphase encoded data. The drivers are pulled
low while the CS8406 is in the reset state.
Master Clock (Input) - The frequency can be set through the control port registers.
Serial Audio Bit Clock (Input/Output) - Serial bit clock for audio data on the SDIN pin.
Serial Audio Input Left/Right Clock (Input/Output) - Word rate clock for the audio data on the SDIN
pin.
Serial Audio Data Port (Input) - Audio data serial input pin.
