Description

Rotates to the left the data whose address is HL.

Each bit moves to the next highest-order bit position (bit 0 moves to bit 1, etc.). Bit 7 moves to both bit 0 and the C flag. See Figure 7 for an illustration.

Example

If HL contains 0x4545, the byte in the memory location 0x4545 is 0110 1010, and the C flag is set, then after the execution of the operation:

RLC (HL)

the byte in memory location 0x4545 will contain 1101 0100 and the C flag will be reset.
