WAND, WANDP, DAND, DANDP

 

WAND instruction performs a bitwise AND operation on Source 1 and Source 2 and places the result in the Destination. The bitwise AND operation returns 1, if the matching bits from both the operands are 1, otherwise it returns 0.

  • WAND(WANDP) is for 16bit source and DAND(DANDP) is for 32bit source.

Example)

If F12 is ON, H3647 moves to D0.

If F10 is ON, the WAND performs a bitwise AND operation by using the 16bits in H3647 (D0) and H651A (D1) and places the result H2402 in the Y20.
