AUTO — Automatic Termination of Program/Erase Cycle
EEPGM — EEPROM-1 Program/Erase Enable
6.5.2 EEPROM-1 Array Configuration Register
The EEPROM-1 array configuration register configures EEPROM-1 security and EEPROM-1 block
protection.
This read-only register is loaded with the contents of the EEPROM-1 nonvolatile register (EE1NVR) after
a reset.
Bit 7:5 — Unused Bits
EEPRTCT — EEPROM-1 Protection Bit
Freescale Semiconductor
When AUTO is set, EEPGM is cleared automatically after the program/erase cycle is terminated by
the internal timer.
(See note D for
Memory
This read/write bit enables the internal charge pump and applies the programming/erasing voltage to
the EEPROM-1 array if the EELAT bit is set and a write to a valid EEPROM-1 location has occurred.
Reset clears the EEPGM bit.
These read/write bits are software programmable but have no functionality.
The EEPRTCT bit is used to enable the security feature in the EEPROM (see EEPROM-1
Program/Erase Protection).
This feature is a write-once feature. Once the protection is enabled it may not be disabled.
1 = Automatic clear of EEPGM is enabled
0 = Automatic clear of EEPGM is disabled
1 = EEPROM-1 programming/erasing power switched on
0 = EEPROM-1 programming/erasing power switched off
1 = EEPROM-1 security disabled
0 = EEPROM-1 security enabled
Characteristics)
Address:
Writing logic 0s to both the EELAT and EEPGM bits with a single instruction
will clear EEPGM only to allow time for the removal of high voltage.
