INSTRUCTION REFERENCE AREA

Using 1-byte REF instructions, you can easily reference instructions with larger byte sizes that are stored in

addresses 0020H–007FH of program memory. This 96-byte area is called the REF instruction reference area, or

look-up table. Locations in the REF look-up table may contain two one-byte instructions, a single two-byte

instruction, or three-byte instructions such as a JP or CALL. The starting address of the instruction you are

referencing must always be an even number. To reference a JP or CALL instruction, it must be written to the

reference area in a two-byte format: for JP, this format is TJP; for CALL, it is TCALL. In summary, there are

three ways to the REF instruction:

— Using the 1-byte REF instruction to execute one 2-byte or two 1-byte instructions,

— Branching to any location by referencing a branch instruction stored in the look-up table,

— Calling subroutines at any location by referencing a call instruction stored in the look-up table.
