When F3X is connected to the internal HP/Line
driver this bit selects the gain of the F3X->analog
out path.
‘0’: HP out. When the MVOL+Channel Vol is
0 dBFs, a 0 dBFs input will generate a 40 mW
output on a 32 ohm load (+/- 3.3V supply).
‘1’: Line out. When the MVOL+Channel Vol is
0 dBFs, a 0 dBFs input will generate a 2 Vrms
output (+/- 3.3 V supply)
‘0’: Charge pump auto-enable when unmute
‘1’: Charge pump is always enabled
‘0’: Charge pump is not working
‘1’: Charge pump is working and it is OK
‘0’: No fault on class-AB
‘1’: Overcurrent fault detected on class-AB
‘1’: Core supply OK
