EEP_ACTIVATE
EEPROM Control Register
Bit[0] = 1h, Start EEPROM Read Procedure
Bit[1] = 1h, Start EEPROM Write Procedure
Bit[5:2] - Reserved
Bit[6] = 1h, Generate Total Checksum (FD data).
Bit[7] = 1h, Generate Individual NVM BANK Checksum (FD data).
The device will declare busy at the assertion of this command, a
new command addressed to this device should be sent 300ms
afterward
When the controller is reset by the Enable pins (TM_EN_OTP or EN_PWR_CFP), not V_CC, the programmed registers will be stored in operating memory.
