RETI
Machine code
Decription
Return from interrupt subroutine
0 0 1 0 1 1 1 1
The program counter bits 0~11 are restored from the stack. The carry flag
before entering the interrupt service routine is restored.

Description
Rotate accumulator left
0 0 0 0 0 0 0 1
The contents of the accumulator are rotated left one bit. Bit 3 is rotated to
both bit 0 and the carry flag.

Description
Rotate accumulator left through carry
0 0 0 0 0 0 1 1
The contents of the accumulator are rotated left one bit. Bit 3 replaces the
carry bit, which is rotated into the bit 0 position.
