Below is an Output assignment example and Timing chart.
[Example assignment of OUTPUT signals]
• Output 1: In Read Cycle
• Output 2: Match (or On Good Read)
Output Mode: Latch Mode 2 (Unlatch Opposite Condition)
• Output 3: Mismatch (or
No Read
)
Output Mode: Latch Mode 2 (Unlatch Opposite Condition)
