Timing Waveform of Semaphore Read after Write Timing, Either Side (1)
Note :
1. CS = VIH for the duration of the above timing (both write and read cycle).
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 guaranted which side will obtain the
flag.
