SWAP [m]
Swap nibbles within the data memory
Description
The low-order and high-order nibbles of the specified data memory (one of
the data memories) are interchanged.
Operation
[m].3~[m].0
[m].7~[m].4

SWAPA [m]
Swap data memory-place result in the accumulator
Description
The low-order and high-order nibbles of the specified data memory are inter-
changed, writing the result to the accumulator. The contents of the data
memory remain unchanged.
Operation
ACC.3~ACC.0
ACC.7~ACC.4
[m].7~[m].4
[m].3~[m].0

Skip if data memory is 0
Description
If the contents of the specified data memory are 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]=0

SZA [m]
Move data memory to , skip if 0
Description
The contents of the specified data memory are copied to the accumulator. If
the contents 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).
Operation
