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
Affected flag(s)
TC2

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

SZ [m]
Skip if data memory is zero
Description
If the contents of the specified data memory are zero, the following instruc-
tion, fetched during the current instruction execution, is discarded and a
dummy cycle is replaced to get the proper instruction (two cycles). Otherwise
proceed with the next instruction (one cycle).
Operation
Skip if [m]=0
Affected flag(s)
TC2

SZA [m]
Move data memory to ACC, skip if zero
Description
The contents of the specified data memory are copied to the accumulator. If
the contents is zero, the following instruction, fetched during the current in-
struction execution, is discarded and a dummy cycle is replaced to get the
proper instruction (two cycles). Otherwise proceed with the next instruction
(one cycle).
Operation
Skip if [m]=0, ACC
