MOV R0n, A

MOV R1n, A

<1> Instruction code

: 0 010 R4 0R3 R2 R1R0

<2> Cycle count

: 1

<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 R1R0

: 0d7 d6 d5 d4 0d3 d2 d1 d0

<2> Cycle count

: 1

<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 R1R0

<2> Cycle count

: 1

<3> Function

: (R1n-R0n)

← ((P13), R0)) n = 1 to F

The program memory contents specified with control register P13 and register pair R10-R00 are

transferred to register pair R1n-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 high-order 2 bits of the program memory address is specified with the control register (P13).
