Notes:
37. CE = HIGH for the duration of the above timing (both write and read cycle).
38. I/O0R = I/O0L = LOW (request semaphore); CER = CEL = HIGH.
39. Semaphores are reset (available to both ports) at cycle start.
40. If tSPS is violated, the semaphore will definitely be obtained by one side or the other, but which side will get the semaphore is unpredictable.
