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-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
TBLPTR[0] = 0: Least Significant Byte of
TBLPTR[0] = 1: Most Significant Byte of
