A
Function:
Rotate accumulator left
Description:
The eight bits in the accumulator are rotated one bit to the left. Bit 7 is rotated into
the bit 0 position. No flags are affected.
Example:
The accumulator holds the value 0C5 H (11000101B). The instruction
RL
leaves the accumulator holding the value 8B H (10001011B) with the carry
unaffected.
Operation:
