<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

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.
