Description

Arithmetically shifts to the left the bits of the data whose address is

• the sum of IX and the 8-bit signed displacement d, or

• the sum of IY and the 8-bit signed displacement d.

Bits 0 through 6 are each shifted to the next highest-order bit position (bit 0 moves to bit 1, etc.). Bit 7 is shifted to the C flag. Bit 0 is reset. See Figure 19 for an illustration.
