RRCA [m]
Rotate right through carry and place result in the accumulator.
Description
Data of the specified data memory and the carry flag are rotated 1 bit right. Bit 0 replaces the
carry bit and the original carry flag is rotated into the bit 7 position. The rotated result is stored
in the accumulator. The contents of the data memory remain unchanged.

Subtract data memory and carry from the accumulator.
Description
The contents of the specified data memory and the complement of the carry flag are sub-
tracted from the accumulator, leaving the result in the accumulator.

Skip if decrement data memory is 0.
Description
The contents of the specified data memory are decremented by 1. If the result is 0, the next in-
struction is skipped. If the result is 0, the following instruction, fetched during the current in-
struction execution, is discarded and a dummy cycle is replaced to get the proper instruction
(2 cycles). Otherwise proceed with the next instruction (1 cycle).

Decrement data memory and place result in ACC, skip if 0.
Description
The contents of the specified data memory are decremented by 1. If the result is 0, the next in-
struction is skipped. The result is stored in the accumulator but the data memory remains un-
changed. If the result is 0, the following instruction, fetched during the current instruction
execution, is discarded and a dummy cycle is replaced to get the proper instruction (2 cycles).
Otherwise proceed with the next instruction (1 cycle).
Operation
Skip if ([m] 1)=0, ACC
