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
