GPIN0 - General-purpose input, PIN 31Q, 37L
Refer to Table 5 below.
GPIN1 - General-purpose input, PIN 32Q, 38L
Refer to Table 5 below.
GPIN2 - General-purpose input, PIN 33Q, 39L
Refer to Table 5 below.
GPIN3 - General-purpose input, PIN 2Q, 8L
Disables 26dB microphone gain when high at reset. Controls Mute after reset. See Table 4 for
more details.
GPOUT0 - General-purpose outputs, PIN 34Q, 40L
GPOUT0 is high when a volume change request is made that exceeds the available range.
GPOUT1 - General-purpose outputs, PIN 35Q, 41L
GPOUT1 is high while the CS6403 is in half-duplex mode during initial convergence.
RESET - System reset, PIN 41Q, 3L
RESET must be asserted high for at least two SCLK periods after powerup to place the CS6403
in a known state.
NC - No Connect, PIN 4Q, 10L
NC must be left floating in normal operation.
