RLC
A
Function:
Rotate accumulator left through carry flag
Description:
The eight bits in the accumulator and the carry flag are together rotated one bit to
the left. Bit 7 moves into the carry flag; the original state of the carry flag moves into
the bit 0 position. No other flags are affected.
Example:
The accumulator holds the value 0C5 H (11000101B), and the carry is zero. The
instruction
RLC
leaves the accumulator holding the value 8A H (10001010B) with the carry set.
Operation:
RLC
(An + 1) ← (An) n = 0-6
(A0) ← (C)
(C) ← (A7)
