VERSION (Read only)
Indicates the silicon revision number.
HPNGTRIP (Read only)
1 = Headphone amplifiers are being muted by the noise gate.
0 = Normal operation.
SPNGTRIP (Read only)
1 = Speaker amplifier is being muted by the noise gate.
0 = Normal operation.
OVRTEMP (Read/Clear)
1 = The junction temperature of the device has exceeded the thermal shutdown threshold. (This bit remains set until it
is read.)
0 = Normal operation.
OVRCURSP (Read/Clear)
1 = The output current limit of the speaker amplifier has been exceeded. (This bit remains set until it is read.)
0 = Normal operation.
