Table 2. Configuration Register Format
DIAG: Set DIAG to 1 to enable diagnostic mode. Write '0' to disable diagnostic mode.
ENABLE: Set ENABLE bit to 1 to enable the device. Write ‘0’ disables the device. Low on the SHDN pin overrides the
ENABLE bit.
MUTE: Set the MUTE bit to 1 to mute both the output channels. Output is low impedance when in mute. Low on the
MUTE pin input overrides the MUTE bit.
OLDL: Write 1 to the OLDL bit to initiate the open-load detection for the left channel. To run OLDL again, write ‘0’ and
‘1’ again.
OLDR: Write 1 to the OLDR bit to initiate the open-load detection for the right channel. To run OLDR again, write ‘0’
and ‘1’ again.
Table 3. Command Byte Register Format
RETRYR: The right-channel power amplifier switches off after a fault condition. Write ‘1’ to turn it back on after the fault
condition.
RETRYL: The left-channel power amplifier switches off after a fault condition. Write ‘1’ to turn on the left-channel power
amplifier after the fault condition.
Table 4. General Fault Register Format
TWARN: The TWARN bit is set to ‘1’ when the temperature warning threshold is reached.
TSHDN: The TSHDN is set to ‘1’ when the temperature shutdown threshold is reached.
DUMP: The DUMP bit is set to ‘1’ when the V
Set the appropriate mask bit in the GMASK register to detect the general faults. See Table 8.
