Notes:
37. CE = HIGH for the duration of the above timing (both write and read cycle).
38. I/O
= I/O
= LOW (request semaphore); CE
= CE
= HIGH.
39. Semaphores are reset (available to both ports) at cycle start.
40. If t
SPS
is violated, the semaphore will definitely be obtained by one side or the other, but which side will get the semaphore is unpredictable.
