Operation:

Description:

Shifts all bits of accumulator B one place to the left. Bit 0 is loaded from the

C status bit. The C bit is loaded from the most significant bit of B. Rotate

operations include the carry bit to allow extension of shift and rotate

operations to multiple bytes. For example, to shift a 24-bit value one bit to

the left, the sequence ASL LOW, ROL MID, and ROL HIGH could be used

where LOW, MID, and HIGH refer to the low-order, middle and high-order

bytes of the 24-bit value, respectively.

N: Set if MSB of result is set; cleared otherwise

Z: Set if result is $00; cleared otherwise

V: N

⊕ C = [N • C] + [N • C] (for N and C after the shift)

Set if (N is set and C is cleared) or (N is cleared and C is set);

cleared otherwise (for values of N and C after the shift)

C: B7

Set if the MSB of B was set before the shift; cleared otherwise
