2: The instructions, TBLRDH/TBLWTH/TBLRDL/TBLWTL, decide if the higher or lower word of program memory is
Data EA<15> is always ‘1’ in this case, but is not used in calculating the program space address. Bit 15 of
the address is DSRPAG<0>.
program memory is read. When DSRPAG<8> is ‘0’, the lower word is read and when it is ‘1’, the higher
word is read.
DSRPAG<9> is always ‘1’ in this case. DSRPAG<8> decides whether the lower word or higher word of
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.
