MOV R0n, A

MOV R1n, A

<1> Instruction code:

0 010 R4 0R3 R2 R1 R0

<2> Cycle count:

<3> Function:

(Rmn)

← (A) m = 0, 1 n = 0 to F

The accumulator contents are transferred to register Rmn.

MOV Rn, #data8

<1> Instruction code:

0 01100 R3 R2 R1 R0

0 d7 d6 d5 d4 0d3 d2 d1 d0

<2> Cycle count:

<3> Function:

(R1n-R0n)

← data8 n = 0 to F

The immediate data is transferred to the register. Using this instruction, registers operate as register

pairs.

The pair combinations are as follows:

R0: R10 - R00

R1: R11 - R01

RE: R1E - R0E

RF: R1F - R0F

MOV Rn, @R0

<1> Instruction code:

0 01110 R3 R2 R1 R0

<2> Cycle count:

<3> Function:

(R1n-R0n)

← ((P13), R0)) n = 1 to F

The program memory contents specified by control register P13 and register pair R10 to R00 are

transferred to register pair R1n to R0n. The program memory consists of 10 bits and has the following

state after the transfer to the register.

@R0

→

R1n

R0n

Program memory

The higher 2 to 4 bits of the program memory address are specified by the control register (P13).
