LSDZ [m]
Skip if decrement Data Memory is 0
Description The contents of the specied Data Memory are rst decremented by 1. If the result is 0 the
following instruction is skipped. As this requires the insertion of a dummy instruction while
the next instruction is fetched, it is a two cycle instruction. If the result is not 0 the program
proceeds with the following instruction.
Operation [m] ← [m] − 1
Skip if [m]=0
Affected ag(s) None
LSDZA [m]
Skip if decrement Data Memory is zero with result in ACC
Description The contents of the specied Data Memory are rst decremented by 1. If the result is 0, the
following instruction is skipped. The result is stored in the Accumulator but the specied
Data Memory contents remain unchanged. As this requires the insertion of a dummy
instruction while the next instruction is fetched, it is a two cycle instruction. If the result is not 0,
the program proceeds with the following instruction.
Operation ACC ← [m] − 1
Skip if ACC=0
Affected ag(s) None
LSET [m]
Set Data Memory
Description Each bit of the specied Data Memory is set to 1.
Operation [m] ← FFH
Affected ag(s) None
LSET [m].i
Set bit of Data Memory
Description Bit i of the specied Data Memory is set to 1.
Operation [m].i ← 1
Affected ag(s) None
LSIZ [m]
Skip if increment Data Memory is 0
Description The contents of the specied Data Memory are rst incremented by 1. If the result is 0, the
following instruction is skipped. As this requires the insertion of a dummy instruction while
the next instruction is fetched, it is a two cycle instruction. If the result is not 0 the program
proceeds with the following instruction.
Operation [m] ← [m] + 1
Skip if [m]=0
Affected ag(s) None
LSIZA [m]
Skip if increment Data Memory is zero with result in ACC
Description The contents of the specied Data Memory are rst incremented by 1. If the result is 0, the
following instruction is skipped. The result is stored in the Accumulator but the specied
Data Memory contents remain unchanged. As this requires the insertion of a dummy
instruction while the next instruction is fetched, it is a two cycle instruction. If the result is not
0 the program proceeds with the following instruction.
Operation ACC ← [m] + 1
Skip if ACC=0
Affected ag(s) None
LSNZ [m].i
Skip if Data Memory is not 0
Description If the specied Data Memory is not 0, the following instruction is skipped. As this requires the
insertion of a dummy instruction while the next instruction is fetched, it is a two cycle
instruction. If the result is 0 the program proceeds with the following instruction.
Operation Skip if [m].i ≠ 0
Affected ag(s) None
