Timing Waveform of
Semaphore Contention (1) (3) (4)
Notes: 1. DOR = DOL VIL, CSR = CSL = VIH, semaphore Flag is released from both sides (reads as ones from both sides) at cycle start.
2. Either side “A’ = left and side “B’ = right, or side “A’ = right and side “B’ = left.
3. This parameter is measured from the point where R/WA or SEMA goes high until R/WB or SEMB goes high.
4. IF tSPS is violated, the semaphore will fall positively to one side or the other, but there is no guarantee which side will obtain
the flag.
