Description: 

This command allows the 32kHz power down mode to be enabled or disabled:  

• 

When power down mode is entered, the product uses a 32kHz internal clock during inactivity 
stages (regardless of its nominal internal clock). 

• 

When enabled, power down mode is active after 1 to 15 minutes. The mode is not stored in 

EEPROM: the command has to be repeated after a reset.
