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