CMPW (Compare Word) is an SPC700 command that performs a comparsion between YA and a 16-bit word in the direct page. Internally, this is done by the ALU subtracting the direct page word from YA, but the difference is not stored anywhere - the side effect is the N, Z, and C flags being modified.

Syntax

CMPW YA, dp
