RLCA [m]  
Rotate left through carry and place result in the accumulator  
Description  
Data in the specified data memory and the carry flag are rotated 1 bit left. Bit 7 replaces the  
carry bit and the original carry flag is rotated into bit 0 position. The rotated result is stored  
in the accumulator but the contents of the data memory remain unchanged.  
Operation  
ACC.(i+1) ¬ [m].i; [m].i:bit i of the data memory (i=0~6)
