Return from subroutine
The program counter is restored from the stack. This is a 2-cycle instruction.
Program Counter ¬ Stack
Return and place immediate data in the accumulator
The program counter is restored from the stack and the accumulator loaded with the speci-

ACC ¬ x
Return from interrupt
The program counter is restored from the stack, and interrupts are enabled by setting the
EMI bit. EMI is the enable master (global) interrupt bit.
Program Counter ¬ Stack
EMI ¬ 1
Rotate data memory left
The contents of the specified data memory are rotated 1 bit left with bit 7 rotated into bit 0.
[m].(i+1) ¬ [m].i; [m].i:bit i of the data memory (i=0~6)
[m].0 ¬ [m].7
Rotate data memory left and place result in the accumulator
Data in the specified data memory is rotated 1 bit left with bit 7 rotated into bit 0, leaving the
rotated result in the accumulator. The contents of the data memory remain unchanged.
ACC.(i+1) ¬ [m].i; [m].i:bit i of the data memory (i=0~6)
ACC.0 ¬ [m].7
