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 5.0 “Flash Program
Memory” for additional details on
programming Flash memory.)
The TBLPTR (a 21-bit pointer) points
to each byte in the program memory.
TBLPTR has a 2-MBtye 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
