Transfers the contents of register B to register A.
Transfers the contents of register A to register B.
Transfers the contents of register Y to register A.
Transfers the contents of register A to register Y.
Transfers the contents of registers A and B to register E.
Transfers the contents of register E to registers A and B.
Transfers the contents of register A to register D.
Transfers the contents of register D to register A.
Transfers the contents of register Z to register A.
Transfers the contents of register X to register A.
Transfers the contents of stack pointer (SP) to register A.
Loads the value x in the immediate field to register X, and the value y in the immediate field to register
Y.
When the LXY instructions are continuously coded and executed, only the first LXY instruction is executed
and other LXY instructions coded continuously are skipped.
Loads the value z in the immediate field to register Z.
Adds 1 to the contents of register Y. As a result of addition, when the contents of register Y is 0, the
next instruction is skipped.
Subtracts 1 from the contents of register Y. As a result of subtraction, when the contents of register Y
is 15, the next instruction is skipped.
