Load value in ’f’ into 16-bit table
latch (TBLAT)
If t = 0: load into low byte;
If t = 1: load into high byte
The contents of TBLAT is written
to the program memory location
pointed to by TBLPTR
If TBLPTR points to external
program memory location, then
the instruction takes two-cycle
If TBLPTR points to an internal
EPROM
instruction is terminated when
an interrupt is received.
The TBLPTR can be automati-
