This instruction is used to read the
contents of Program Memory (P.M.). To
address the program memory, a
pointer called Table Pointer (TBLPTR)
is used.
The TBLPTR (a 21-bit pointer) points
to each byte in the program memory.
TBLPTR has a 2 Mbyte address range.
The TBLRD instruction can modify the
value of TBLPTR as follows:
• no change
• post-increment
• post-decrement
• pre-increment
