25.3 FNC194~199 – BKCMP=, >, <, < >, <=, >= / Block Data Compare
25.3 FNC194~199 – BKCMP=, >, <, < >, <=, >= / Block Data Compare
Outline
These instructions compare block data in the comparison condition set in each instruction.
1. Instruction format
2. Set data (common among FNC194 to FNC199)
3. Applicable devices (common among FNC194 to FNC199)
S: "D.b" cannot be indexed with index registers (V and Z).
