Detailed Description

EEPROM values can only be changed if the input voltage (VIN_BIAS) is greater than 4.5 V. If the input

voltage is less than 4.5 V, EEPROM values remain unchanged and the VPROG interrupt is issued.

EEPROM programming requires less than 100 ms. During this time the supply voltage must be held

constant and all I2C write commands are ignored. Completion of EEPROM programming is signaled by

the EE_CMPL interrupt.
