LSZ [m].i
Skip if bit i of Data Memory is 0
Description If bit i of the specied Data Memory 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 Skip if [m].i=0
Affected ag(s) None
LTABRD [m]
Read table (current page) to TBLH and Data Memory
Description The low byte of the program code (current page) addressed by the table pointer (TBLP) is
moved to the specied Data Memory and the high byte moved to TBLH.
Operation [m] ← program code (low byte)
TBLH ← program code (high byte)
Affected ag(s) None
LTABRDL [m]
Read table (last page) to TBLH and Data Memory
Description The low byte of the program code (last page) addressed by the table pointer (TBLP) is moved
to the specied Data Memory and the high byte moved to TBLH.
Operation [m] ← program code (low byte)
TBLH ← program code (high byte)
Affected ag(s) None
LITABRD [m]
Increment table pointer low byte rst and read table to TBLH and Data Memory
Description Increment table pointer low byte, TBLP, rst and then the program code addressed by the
table pointer (TBHP and TBLP) is moved to the specied Data Memory and the high byte
moved to TBLH.
Operation [m] ← program code (low byte)
TBLH ← program code (high byte)
Affected ag(s) None
LITABRDL [m]
Increment table pointer low byte rst and read table (last page) to TBLH and Data Memory
Description Increment table pointer low byte, TBLP, rst and then the low byte of the program code
(last page) addressed by the table pointer (TBLP) is moved to the specied Data Memory and
the high byte moved to TBLH.
Operation [m] ← program code (low byte)
TBLH ← program code (high byte)
Affected ag(s) None
LXOR A,[m]
Logical XOR Data Memory to ACC
Description Data in the Accumulator and the specied Data Memory perform a bitwise logical XOR
operation. The result is stored in the Accumulator.
Operation ACC ← ACC ″XOR″ [m]
Affected ag(s) Z
LXORM A,[m]
Logical XOR ACC to Data Memory
Description Data in the specied Data Memory and the Accumulator perform a bitwise logical XOR
operation. The result is stored in the Data Memory.
Operation [m] ← ACC ″XOR″ [m]
Affected ag(s) Z
