TIP #15 Delay Techniques (Cont.)
For a two cycle delay, it is common to use two
NOP instructions which uses two program
memory locations. The same result can be
achieved by using “goto $+1”. The “$” represents
the current program counter value in MPASM.
When this instruction is encountered, the MCU will
jump to the next memory location. This is what it
would have done if two NOP’s were used but since
the “goto” instruction uses two instruction cycles to
execute, a two cycle delay was created. This
created a two cycle delay using only one location
of program memory.
To create a four cycle delay, add a label to an
existing “RETURN” instruction in the code. In this
example, the label “Rtrn” was added to the
“RETURN” of subroutine that already existed
somewhere in the code. When executing “CALL
Rtrn”, the MCU delays two instruction cycles to
execute the “CALL” and two more to execute the
“RETURN”. Instead of using four “NOP”
instructions to create a four cycle delay, the same
result was achieved by adding a single “CALL”
instruction.
