Fixed cycle delay

Delay code

Shortest possible CPU code that creates N cycles of delay, depending on constraints.

All code samples are written for CA65.

Assumptions:

• No page wrap occurs during any branch instruction. If a page wrap occurs, it adds +1 cycle for each loop, completely thwarting the accurate delay.
• No interrupt / NMI occurs during the delay code. This is important for accurate delay, but it is also required for correctness in those code samples where a PLA-PHA sequence is used.

It is possible to verify on compile time that no page wrap occurs, by replacing all branches with these macros:

.macro branch_check opc, dest
    opc dest
    .assert >* = >dest, warning, "branch_check: failed, crosses page"
.endmacro
.macro Jcc dest
        branch_check bcc, dest
.endmacro
.macro Jcs dest
        branch_check bcs, dest
.endmacro
.macro Jeq dest
        branch_check beq, dest
.endmacro
.macro Jne dest
        branch_check bne, dest
.endmacro
.macro Jmi dest
        branch_check bmi, dest
.endmacro
.macro Jpl dest
        branch_check bpl, dest
.endmacro
.macro Jvc dest
        branch_check bvc, dest
.endmacro
.macro Jvs dest
        branch_check bvs, dest
.endmacro

It is permissible for DMA to steal cycles during the loops. If you are expecting that to happen, you have to manually adjust the delay cycle count (and it is in fact possible to do so) in order to get the correct delay.

Explanations on the requirements:

• @zptemp means you have a zeropage address that you can write random data into.
• @rti means you have a dummy interrupt handler installed that does nothing but RTI.
• @rts12 means you know a memory address that contains byte $60 (RTS).
• @rts14 means you know a memory address that contains a harmless 2-cycle instruction that fits your constraints (such as CLC, LDA #0, or NOP), followed by RTS.
• @rts15 means you know a memory address that contains a JMP that jumps to another location that contains RTS. Alternatively, it means you know a memory address that contains a harmless 3-cycle instruction that fits your constraints (such as LDA $00), followed by RTS.
• delay_a_25_clocks, delay_256a_16_clocks, delay_256a_x_33_clocks, delay_256a_x_31_clocks, and delay_256x_a_30_clocks are defined at Delay code.

EA NOP	No requirements

• All instructions cost at least 2 cycles. There is no way to do 1 cycle of delay (though −1 cycles may sometimes appear in branch cost calculations).

• Not relocatable means that the target address is hardcoded into the code. In ROM hacking, it sometimes makes sense to move code blobs around, and a hardcoded address makes it difficult to relocate the code. This restriction does not apply to branches, which use relative addressing. It is also assumed to not apply to JSR instructions, as chances are the JSR target is outside the code being relocated.

EA ... NOP × 2	No requirements

• zp-indexed modes such as LDA $00,X also do 4 cycles, but having side effects, these two-byte instructions are inferior to a simple 2 × NOP.
• There is also an unofficial opcode NOP $00,X (34 00), but there is no reason to use this instruction when the official equivalent has the same performance.

• abs-indexed modes such as LDA $1234,X cause 4 or 5 cycles of delay, depending whether a page wrap occurred. Because you need extra setup code to make sure that a wrap does occur, you do not see this mode in these samples, outside situations where circumstances permit.

EA ... NOP × 3	No requirements

• zp-indexed RMW instructions such as INC @zptemp,X do 6 cycles, but as the memory address modified depends on the value of X, and in this document it is a bit difficult to formalize the rules under which you can write to such addresses, thus the instruction is not used.
• ix and iy instructions such as LDA ($00,X) or LDA ($00),Y do 6 cycles, but there may be side effects for reading from random memory addresses (such as $2002), and therefore we do not do that. With ind-y there is also the trouble of predicting whether a wrap occurs or not.
• Absolute RMW instructions like INC $2000 do 6 cycles, but weighing 3 bytes with side-effects it would be inferior to 3 × NOP.

• PHP-PLP is very efficient for 7 cycles of delay, but it does modify stack contents. S register remains unchanged though.
• PLA-PHA does not overwrite any bytes in stack. It just writes back the same byte. But it does clobber A and Z+N.
• abs-indexed RMW instructions such as INC abs,X do 7 cycles, but it is difficult to formalize the rules under which one could write to such random addresses.

• ix and iy RMW instructions such as SLO ($00,X) or SLO ($00),Y would do 8 cycles for 2 bytes of code, but it is dangerous to read random memory addresses, let alone write to them, so we do not do that. These instructions are also unofficial.

• JSR-RTS causes 12 cycles of delay. But it does write a function return address in the stack, which may be unwanted in some applications. S is not modified.
• Again, ROL-ROR does not have side effects (as long as an interrupt does not happen in the middle), except for Z+N.
