MC68HC812A4 Datasheet, PDF (119/342 Pages) Motorola, Inc – 16-bit device composed of standard on-chip peripheral modules connected by an intermodule bus. Modules include

EEPROM
EEPROM Control Registers
A program or erase operation should follow this sequence:
1. Write BYTE, ROW, and ERASE to the desired value; write
EELAT = 1.
2. Write a byte or an aligned word to an EEPROM address.
3. Write EEPGM = 1.
4. Wait for programming (t_PROG) or erase (t_Erase) delay time.
5. Write EEPGM = 0.
6. Write EELAT = 0.
By jumping from step 5 to step 2, it is possible to program/erase more
bytes or words without intermediate EEPROM reads.
