GPIO0 Output Selection – These bits select the signal to output to GPIO0. To actually output the selected signal, the GPIO0 must be set to output mode at P0-R8.
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 ** INTERNAL **
1100: Short detection flag for left channel
1101: Short detection flag for right channel
10000: PLL clock/4
10001: Oscillator clock/4
10010: Impedance sense flag for left channel
10011: Impedance sense flag for right channel
10100: Internal UVP flag, becomes low when VDD falls below roughly 2.7V
10101: Offset calibration flag, asserted when the system is offset calibrating itself.
10110: Clock error flag
10111: Clock changing flag
11000: Clock missing flag
11001: Clock halt detection flag
11010: DSP boot done flag
11011: Charge pump voltage output valid flag (low active)
Others: N/A (zero)
