GPIO3 Output Selection

These bits select the signal to output to GPIO3. To actually output the selected signal, the GPIO3 must be set

to output mode at Page 0 / Register 8.

Default value: 00000

0000: off (low)

0001: DSP GPIO3 output

0010: Register GPIO3 output (Page 0 / Register 86, bit 2)

00011: Auto mute flag (asserted when both L and R channels are auto muted)

00100: Auto mute flag for left channel

00101: Auto mute flag for right channel

00110: Clock invalid flag (clock error or clock changing or clock missing)

00111: Serial audio interface data output (SDOUT)

01000: Analog mute flag for left channel (low active)

01001: Analog mute flag for right channel (low active)

01010: PLL lock flag

01011: Charge pump clock
