RotateDataMemoryleftthroughCarrywithresultin ACC

Description

Data in the specified Data Memory and the carry flag are rotated left by 1 bit. Bit 7 replaces

the Carry bit and the original carry flag is rotated into the bit 0. The rotated result is stored in

theAccumulatorandthecontentsoftheDataMemoryremainunchanged.
