1=Indicates that the speaker amplifier current limit of 1.3A_PEAK has been exceeded. Speaker amplifier turns off. Bit
remains HIGH and amplifier stays off until power or SRST are cycled.
0=Normal operation.
OTP_ERR
(Read only)
1=Indicates that the temperature limit of 150°C has been exceeded. Speaker amplifier turns off. Bit remains HIGH
and amplifier stays off until temperature falls below thermal shutdown hysteresis (see Electrical Characteristics) or
power or SRST are cycled.
0=Normal operation.
DC_ERR
(Read only)
1=Indicates that the DC voltage across the speaker amplifier terminals has exceeded 1.5V_pk. Speaker amplifier turns
off. Bit remains high and amplifier stays off until power or SRST are cycled.
0=Normal operation.
