Timing Waveform of Semaphore Read after Write Timing, Either Side
Timing Waveform of Semaphore Write Contention
NOTES:
1. D
2. All timing is the same for left and right ports. Port “A” may be either left or right port. “B” is the opposite from port “A”.
3. This parameter is measured from R/W
4. If t
