PIC18F6525/6621/8525/8621
5.2.2
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.
5.2.3
The Table Pointer register (TBLPTR) 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). These three regis-
ters 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, TBLPTR, is used by the TBLRD and
TBLWT instructions. These instructions can update the
TBLPTR in one of four ways based on the table opera-
tion. These operations are shown in Table 5-1. These
operations on the TBLPTR only affect the low-order
21 bits.

5.2.4
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 a TBLWT is executed, the three LSbs of the Table
Pointer register (TBLPTR<2:0>) determine which of the
eight program memory holding registers is written to.
When the timed write to program memory (long write)
begins, the 19 MSbs of the TBLPTR (TBLPTR<21:3>)
will determine which program memory block of 8 bytes
is written to. For more detail, see Section 5.5 “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 5-3 describes the relevant boundaries of
TBLPTR based on Flash program memory operations.
