The accumulator contents are transferred to register Rmn.
The immediate data is transferred to the register. Using this instruction, registers operate as register
pairs.
The pair combinations are as follows:
The program memory contents specified with control register P13 and register pair R
transferred to register pair R1n-R0n. The program memory consists of 10 bits and has the following
state after the transfer to the register.
The high-order 2 bits of the program memory address is specified with the control register (P13).
