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.
CPOFF: Set the CPOFF bit to 1 to turn off the charge pump. CHOLD pin must be externally supplied (see the V
parameter in the Electrical Characteristics table). Charge pump is enabled when CPOFF = 0.
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.
CPF[1:0]: Sets the frequency of the charge pump.
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.
