7.5.2.3 EEPROM Programming

After the EEPROM is unlocked, a write to any EEPROM-associated register triggers EEPROM programming. A programming event takes up to 16 ms, depending on the device conditions; therefore, space out successive commands in 16-ms write periods.

Poll BUSY (bit 1 in the temperature register) to check the EEPROM programming status. The BUSY bit = 1 when the EEPROM program is in progress. The BUSY bit = 0 after programming is complete and the EEPROM is ready for another program operation. While the EEPROM is being programmed, writes to every other register are prevented in order to protect device data from corruption until programming is complete.

When the global write operation is issued to program the EEPROM locations, all of the devices in the daisy chain specified within the address field perform the programming simultaneously. This simultaneous programming leads to an increase in current in the supply wire of the daisy chain, and may create a drop in the supply voltage. It is important to maintain the supply voltage at greater than 1.8 V during the EEPROM programming in order to program devices in the daisy chain.
