Table 7. Flag Register Format
FLAG: FLAG bit is set to ‘1’ when the FLAG output is logic-low. The FLAG bit allows to quickly access the status of the
device without using the FLAG output and without having to read all the fault registers.
LHIGHZ: The LHIGHZ bit is set to ‘1’ when the left-channel output is high impedance; for example due to a short circuit.
RHIGHZ: The RHIGHZ bit is set to ‘1’ when the right-channel output is high impedance; for example due to a short
circuit.
OFFSETL: The OFFSETL bit is set to ‘1’ when excessive offset is detected on the left-channel output.
OFFSETR: The OFFSETR bit is set to ‘1’ when excessive offset is detected on the right-channel output.
ID[2:0]: The ID[2:0] bits indicate the device type (12dB = 100 and 0dB = 101).
Table 8. General Mask Register Format
MTWARN: Set MTWARN to ‘1’ to enable the TWARN fault detection. See Table 4.
MTSHDN: Set MTSHDN to ‘1’ to enable the TSHDN fault detection. See Table 4.
MDUMP: Set MDUMP to ‘1’ to enable the DUMP fault detection. See Table 4.
Table 9. Left-Channel Mask Register
MSVDDL: Set MSVDDL to 1 to enable the short to V
MSGNDL: Set MSGNDL to 1 to enable the short to GND detection on the left channel.
MLIMITL: Set MLIMITL to 1 to enable overcurrent detection on the left channel.
MOFFSETL: Set MOFFSETL to 1 to enable excessive-offset detection on the left-channel output.
MOPENL: Set MOPENL to 1 to enable open-load detection on the left channel.
