Set Data Memory

Each bit of the specified Data Memory is set to 1.

[m] ← FFH

None

Set bit of Data Memory

Bit i of the specified Data Memory is set to 1.

[m].1 ← 1

None

Skip if increment Data Memory is 0

The contents of the specified Data Memory are first incremented by 1. If the result

is 0, the following instruction is skipped. As this requires the insertion of a dummy

instruction while the next instruction is fetched, it is a two cycle instruction. If the

result is not 0 the program proceeds with the following instruction.

[m] ← [m] + 1

Skip if [m] = 0

None

Skip if increment Data Memory is zero with result in ACC

The contents of the specified Data Memory are first incremented by 1. If the result

is 0, the following instruction is skipped. The result is stored in the Accumulator

but the specified Data Memory contents remain unchanged. As this requires the

insertion of a dummy instruction while the next instruction is fetched, it is a two

cycle instruction. If the result is not 0 the program proceeds with the following

instruction.

ACC ← [m] + 1

Skip if ACC = 0

None

Skip if bit i of Data Memory is not 0

If bit i of the specified Data Memory is not 0, the following instruction is skipped.

As this requires the insertion of a dummy instruction while the next instruction is

fetched, it is a two cycle instruction. If the result is 0 the program proceeds with

the following instruction.

Skip if [m].i ≠ 0

None

Subtract Data Memory from ACC

The specified Data Memory is subtracted from the contents of the Accumulator.

The result is stored in the Accumulator. Note that if the result of subtraction is

negative, the C flag will be cleared to 0, otherwise if the result is positive or zero,

the C flag will be set to 1.

ACC ← ACC − [m]
