NOTE
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 mode. Block
protect register bits can be written to one (protection enabled) at any time.
BULKP — Bulk Erase of EEPROM Protect
0 = EEPROM can be bulk erased normally
1 = EEPROM cannot be bulk or row erased
LVPEN — Low Voltage Programming Protect Enable
If LVPEN = 1, programming of the EEPROM is enabled unless the LVPI circuit detects that V
DD
has
fallen below a safe operating voltage thus setting the low voltage programming inhibit bit in PPROG reg-
ister (LVPI = 1).
0 = Low voltage programming protect for EEPROM disabled
1 = Low voltage programming protect for EEPROM enabled
BPRT[4:0] —Block Protect Bits for EEPROM
0 = Protection disabled
1 = Protection enabled
PTCON — Protect for CONFIG
0 = CONFIG register can be programmed or erased normally
1 = CONFIG register cannot be programmed or erased
INIT2 can be written only once in normal modes, any time in special modes.
EE[3:0] — EEPROM Map Position
EEPROM is at $xD80–$xFFF, where x is the hexadecimal digit represented by EE[3:0] bits.
Bits [3:0] — Not implemented
Always read zero
