SIZA [m]
Increment data memory and place result in ACC, skip if zero
Description
The contents of the specified data memory is incremented by one. If the
result is zero, the next instruction is skipped and the result stored in the
accumulator. The data memory remains unchanged. If the result is zero,
the following instruction, fetched during the current instruction execu-
tion, is discarded and a dummy cycle replaced to get the proper instruc-
tion. This is a 2-cycle instruction. Otherwise proceed with the next
instruction.

Skip if bit i of the data memory is not zero
Description
If bit i of the specified data memory is not zero, the next instruction is
skipped. If bit i of the data memory is not zero, the following instruction,
fetched during the current instruction execution, is discarded and a
dummycycleisreplacedtogettheproperinstruction.Thisisa2-cyclein-
