SDZA [m]
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 instruction is skipped. The result is stored in the accumulator
but the data memory remains unchanged. If the result is 0, the following in-
struction, 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
([m] 1)

SIZ [m]
Skip if increment data memory is 0
Description
The contents of the specified data memory are incremented by 1. If the result
is 0, the following instruction, fetched during the current instruction execu-
tion, 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, [m]
