Programming

delay between the end of the writing sequence and the start of programming.

Typical programming time is 5.6ms. This cycle includes a data verification read to grant secure and correct programming.

After successful programming, the Atmel ATA5575M1 enters byte read mode, transmitting the byte just programmed.

After validation of the command sequence, the new data will be programmed into the EEPROM memory.

Each programming cycle consists of four consecutive steps: erase byte, erase verification (data = 0), programming,

programming verification (corresponding data bits = 1).
