Continuous
description
–
–
Loads the value n in the immediate field to register A.
When the LA instructions are continuously coded and executed, only the first LA instruction is executed
and other LA instructions coded continuously are skipped.
–
Transfers bits 7 to 4 to register B and bits 3 to 0 to register A when URS flag is cleared to “0.” These bits
7 to 0 are the ROM pattern in address (DR2 DR1 DR0 A3 A2 A1 A0) specified by registers A and D in
page p.
0/1 Transfers bit 8 of ROM pattern is transferred to flag CY when URS flag is set to “1” (after the URSC
instruction is executed).
(One of stack is used when the TABP p instruction is executed.)
–
–
Adds the contents of M(DP) to register A. Stores the result in register A. The contents of carry flag CY
remains unchanged.
–
0/1 Adds the contents of M(DP) and carry flag CY to register A. Stores the result in register A and carry flag
CY.
Overflow = 0
–
Adds the value n in the immediate field to register A.
The contents of carry flag CY remains unchanged.
Skips the next instruction when there is no overflow as the result of operation.
–
1
0
–
–
Sets (1) to carry flag CY.
–
Clears (0) to carry flag CY.
(CY) = 0
Skips the next instruction when the contents of carry flag CY is “0.”
Stores the one‘s complement for register A‘s contents in register A.
–
–
–
0/1 Rotates 1 bit of the contents of register A including the contents of carry flag CY to the right.
–
Executes the logic operation selected by logic operation selection register LO between the contents of
register A and register E, and stores the result in register A.
