This instruction is used to program the
contents of Program Memory (P.M.).
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
