LVPI —Low Voltage Programming Inhibit
BYTE —Byte/Other EEPROM Erase Mode
ROW —Row/All EEPROM Erase Mode (only valid when BYTE = 0)
ERASE —Erase/Normal Control for EEPROM
EELAT —EEPROM Latch Control
EEPGM —EEPROM Program Command
BPROT — Block Protect
BULKP —Bulk Erase of EEPROM Protect
M68HC11 K Series
MC6HC11KTS/D
RESET:
LVPI can be read at any time and writes to LVPI have no meaning nor effect. LVPI is set if LVPEN bit
in BPROT register equals one and the LVPI circuit detects that V
voltage. Once set, LVPI is cleared when V
BPROT register is cleared. If LVPEN equals zero, then LVPI is always zero and has no meaning nor
effect.
0 = EEPROM programming enabled
1 = EEPROM programming disabled
0 = Row or bulk erase mode used
1 = Erase only one byte of EEPROM
0 = All 640 bytes of EEPROM erased
1 = Erase only one 16-byte row of EEPROM
0 = Normal read or program mode
1 = Erase mode
0 = EEPROM address and data bus configured for normal reads
1 = EEPROM address and data bus configured for programming or erasing
0 = Program or erase voltage switched off to EEPROM array
1 = Program or erase voltage switched on to EEPROM array
0 = EEPROM can be bulk erased normally
1 = EEPROM cannot be bulk or row erased
BULKP
Bit 7
1
Block protect register bits can be written to zero (protection disabled) only once
within 64 cycles of a reset in normal modes, or at any time in special modes. Block
protect register bits can be written to one (protection enabled) at any time.
