MOV SImm,[d]

Transfer (SImm→[destination])

Operation details

Transfers SIMm data to the RAM or register specified by [destination].

SImm data is signed 8-bit data.

flag

[d] Area selected by selection; Imm data.

remarks

[MCx(x=0~3)] specifies DATA RAMx(x0~3), and after transfer, increments [CTx(x=0~3)].

MOV [s],[d]

Transfer ([source]→[destination])

Operation details

Transfers the data in the RAM or register specified by [source] to the RAM or register specified by [destination].

descriptive formula

label: MOV [source],[destination]

Source = MC0～MC3,MC0～MC3,ALH,ALL
Destination = MC0~MC3,RX,PL,RA0,WA0,LOP,TOP,TC0~TC3

flag

[d] Area selected by the option; [s] Data for the area selected by the option.

remarks

[Mx(x=0~3)] specifies DATA RAMx(x0~3).

[MCx(x=0~3)] specifies DATA RAMx(x0~3), and increments [CTx(x=0~3)] after transfer.
