• Manufacturer Part Number: mc68hc711k4
• Description: Hcmos Microcontroller Unit
• Manufacturer: Freescale Semiconductor, Inc

M68HC11K Family
MOTOROLA
NOTE:
LVPI — Low-Voltage Programming Inhibit Bit
BYTE — Byte/Other EEPROM Erase Mode Bit
ROW — Row/All EEPROM Erase Mode Bit
ROW is valid only when BYTE = 0.
The BYTE and ROW bits work together to determine the scope of
erasing, as shown in
ERASE — Erase/Normal Control for EEPROM Bit
EELAT — EEPROM Latch Control Bit
EEPGM — EEPROM Program Command Bit
LVPI is a read-only bit which always reads as 0. The functionality of
this status bit was changed from early versions of the M68HC11K
Family. The low-voltage programming inhibit function is disabled on
all recent devices.
