PIC18CXX2
5.1
Several control registers are used in conjunction with
the TBLRD and TBLWT instructions. These include the:
• TBLPTR registers
• TABLAT register
• RCON register

RCON REGISTER (ADDRESS: FD0h)
bit 7
IPEN: Interrupt Priority Enable bit
1 = Enable priority levels on interrupts
0 = Disable priority levels on interrupts (16CXXX compatibility mode)
LWRT: Long Write Enable bit
1 = Enable TBLWT to internal program memory
0 = Disable TBLWT to internal program memory.
Note:
Unimplemented: Read as '0'
RI: RESET Instruction Flag bit
1 = No RESET instruction occurred
0 = A RESET instruction occurred
TO: Time-out bit
1 = After power-up, CLRWDT instruction, or SLEEP instruction
0 = A WDT time-out occurred
PD: Power-down bit
1 = After power-up or by the CLRWDT instruction
0 = By execution of the SLEEP instruction
POR: Power-on Reset Status bit
1 = No Power-on Reset occurred
0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
BOR: Brown-out Reset Status bit
1 = No Brown-out Reset or POR Reset occurred
0 = A Brown-out Reset or POR Reset occurred
Legend:
R = Readable bit
- n = Value at POR reset
R/W-0
IPEN
(must be set in software after a Brown-out Reset occurs)
Only cleared on a POR or MCLR Reset.
This bit has no effect on TBLWTs to external program memory.

5.1.1
The LWRT bit specifies the operation of Table Writes to
internal memory when the V
MCLR pin. When the LWRT bit is set, the controller
continues to execute user code, but long Table Writes
are allowed (for programming internal program mem-
ory) from user mode. The LWRT bit can be cleared only
by performing either a POR or MCLR Reset.
