PIC18F1230/1330
7.2.2
The Table Latch (TABLAT) is an 8-bit register mapped
into the SFR space. The Table Latch register is used to
hold 8-bit data during data transfers between program
memory and data RAM.
7.2.3
The Table Pointer (TBLPTR) register addresses a byte
within the program memory. The TBLPTR is comprised
of three SFR registers: Table Pointer Upper Byte,
Table Pointer High Byte and Table Pointer Low Byte
(TBLPTRU:TBLPTRH:TBLPTRL).
registers join to form a 22-bit wide pointer. The low-
order 21 bits allow the device to address up to
2 Mbytes of program memory space. The 22nd bit
allows access to the device ID, the user ID and the
Configuration bits.
The Table Pointer register, TBLPTR, is used by the
TBLRD and TBLWT instructions. These instructions can
update the TBLPTR in one of four ways based on the
table operation. These operations are shown in
Table 7-1. These operations on the TBLPTR only affect
the low-order 21 bits.

7.2.4
TBLPTR is used in reads, writes and erases of the
Flash program memory.
When a TBLRD is executed, all 22 bits of the TBLPTR
determine which byte is read from program memory
into TABLAT.
When the timed write to program memory begins (via
the WR bit), the 19 MSbs of the TBLPTR
(TBLPTR<21:3>) determine which program memory
block of 8 bytes is written to. The Table Pointer regis-
ter’s three LSBs (TBLPTR<2:0>) are ignored. For more
detail, see Section 7.5 “Writing to Flash Program
Memory”.
When an erase of program memory is executed, the
16 MSbs of the Table Pointer register (TBLPTR<21:6>)
point to the 64-byte block that will be erased. The Least
Significant bits (TBLPTR<5:0>) are ignored.
Figure 7-3 describes the relevant boundaries of
TBLPTR based on Flash program memory operations.
