Function:
Rotate accumulator right through carry flag

The eight bits in the accumulator and the carry flag are together rotated one bit to
the right. Bit 0 moves into the carry flag; the original value of the carry flag moves
into the bit 7 position. No other flags are affected.
Example:
The accumulator holds the value 0C5 H (11000101 B ), the carry is zero. The
instruction

leaves the accumulator holding the value 62 H (01100010 B ) with the carry set.
