DSRPAG<8> acts as word select. DSRPAG<9> should always be ‘1’ to map program memory to data memory.
The instructions, TBLRDH/TBLWTH/TBLRDL/TBLWTL, decide if the higher or lower word of program memory is
accessed. TBLRDH/TBLWTH instructions access the higher word and TBLRDL/TBLWTL instructions access the
lower word. Table Read operations are permitted in the configuration memory space.
