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
register (LVPI = 1).
0 = Low voltage programming protect for EEPROM disabled
1 = Low voltage programming protect for EEPROM enabled
BPRT4 —Block Protect Bit for Upper 128 Bytes of EEPROM
Refer to description for BPRT[3:0].
PTCON —Protect for CONFIG
0 = CONFIG register can be programmed or erased normally
1 = CONFIG register cannot be programmed or erased
BPRT[3:0] —Block Protect Bits for EEPROM
0 = Protection disabled
1 = Protection enabled
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 [3:0] —Not implemented
Always read zero
3.5 Configuration Control Register (CONFIG)
The CONFIG register is used to define several system functions. Although the CONFIG register is an
address within the register block, it is actually an EEPROM byte with the address of $x03F. CONFIG is
made up of EEPROM cells and static latches. The operation of the MCU is controlled directly by these
latches and not the actual EEPROM byte. When programming the CONFIG register, the EEPROM byte
is being accessed. When the CONFIG register is being read, the static latches are being accessed.
The CONFIG register can be read at any time. The value read is the one latched from the EEPROM
cells during the last reset sequence. A new value programmed into this register cannot be read until a
subsequent reset occurs. Unused bits always read as ones.
In normal modes (SMOD = 0), CONFIG bits can only be written using the EEPROM programming se-
quence, and are neither readable nor active until latched via the next reset. In special modes (SMOD =
1), CONFIG bits can be written at any time.
