This operation shifts all the bits of the accumulator one bit left. Bit 0 is set to 0 and bit 7 is placed in the carry flag. The effect of this operation is to multiply the memory contents by 2 (ignoring 2's complement considerations), setting the carry if the result will not fit in 8 bits.
C Carry Flag Set to contents of old bit 7 Z Zero Flag Set if A = 0 I Interrupt Disable Not affected D Decimal Mode Flag Not affected B Break Command Not affected V Overflow Flag Not affected N Negative Flag Set if bit 7 of the result is set
