The STORE_USER_ALL command stores all of the current storable register settings in the EEPROM memory as the new defaults on power up.

It is permissible to use this command while the device is switching. Note however that the device continues to switch but ignores all fault conditions until the internal store process has completed.

EEPROM programming faults cause the device to NACK and set the 'cml' bit in the STATUS_BYTE and the 'oth' bit in the STATUS_CML registers.
