MOV[s],X

Transfer (memory → [RX])

Operation details

Data is transferred from the data RAM at the address indicated by [CTx(x=0 to 3)] to [RX].

descriptive formula

label: MOV[Source RAM],X

Source RAM=M0～M3,MC0～MC3

flag

RX;This will be the data selected in the options.

CTx(x=0~3);Incremented only when b22=1. There is no change when b22=0.

remarks

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

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

MOV MUL,P

Transfer (MULTIPLIER→[Pn])

Operation details

Transfer the upper 16 bits of 48 bits of MULTIPLIER data to [PH] and the lower 32 bits to [PL].

MOV[s],P

Transfer (memory → [PH])

Operation details

Transfer data from the data RAM at the address indicated by [CTx(x=0 to 3)] to [PL].

flag

PL;This will be the data selected in the options.

Changes with sign extension of PH;[PL]. To do.

CTx(x=0~3);Incremented only when b22=1. There is no change when b22=0.

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.
