The SAFE command is sets the settings for the low-voltage detection and temperature detection functions.
The BLD2–0 bits are used to set the power supply voltage detection level.
The judgment voltage can be
selected from among six levels from 2.7 to 4.0 V.
The power supply voltage is monitored each time it reaches
the value set by TM2–0, and if the power supply voltage reaches or falls below the set detection voltage two
times or more, the ERR pin outputs a ”H” level and the RDSTAT command’s BLDERR bit is set to ”1”.
If the ERR pin is set to a ”H” level, check the error contents using the RDSTAT command.
If the BLDERR bit
is at ”1”, it is possibly a power supply related failure.

The TSD1–0 bits are used to set the temperature detection level.
Tj=140
°C or OFF can be selected as the
judgment temperature.
The temperature is monitored each time it reaches the value set by TM2–0, and if the
temperature
reaches or exceeds the set value two times or more, the ERR pin outputs a ”H” level and the
RDSTAT command’s TSDERR bit is set to ”1”.
If the ERR pin is set to a ”H” level, check the error contents using the RDSTAT command.
If the TSDERR bit
is at ”1”, reduce the volume using the AVOL command or put the analog section into the power down state
using the AMODE command.
