G3SL[3:0] 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: 0000
0000: off (low)
0001: DSP GPIO3 output
0010: Register GPIO3 output (Page 0 / Register 86, bit 2)
0011: Auto mute flag (asserted when both L and R channels are auto muted)
0100: Auto mute flag for left channel
0101: Auto mute flag for right channel
0110: Clock invalid flag (clock error or clock changing or clock missing)
0111: Serial audio interface data output (SDOUT)
1000: Analog mute flag for left channel (low active)
1001: Analog mute flag for right channel (low active)
1010: PLL lock flag
1011: Charge pump clock
1100: Reserved
1101: Reserved
1110: Under voltage flag, asserted when XSMUTE voltage is higher than 0.7 DVDD
1111: Under voltage flag, asserted when XSMUTE voltage is higher than 0.3 DVDD

to output mode at Page 0 / Register 8.
Default value: 0000
0000: off (low)
0001: DSP GPIO4 output
0010: Register GPIO4 output (Page 0 / Register 86, bit 3)
