Return and place immediate data in the accumulator
The program counter is restored from the stack and the accumulator loaded
with the specified 8-bit immediate data.

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 (bit 0;
register INTC).
PC ← Stack
EMI ← 1

Rotate data memory left
The contents of the specified data memory are rotated one 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 one 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)
