This instruction uses the 3 LSBs of TBLPTR to
determine which of the 8 holding registers the
TABLAT is written to. The holding registers are
used to program the contents of Program
Memory (P.M.). (Refer to Section 6.0 “Flash
Program Memory” for additional details.)
The TBLPTR (a 21-bit pointer) points to each
byte in the program memory. TBLPTR has a
2-Mbyte address range. The LSb of the
TBLPTR selects which byte of the program
memory location to access.
The TBLWT instruction can modify the value
of TBLPTR as follows:
• no change
• post-increment
• post-decrement
• pre-increment
