Waveform of BUSY Arbitration Controlled by CE Timing (M/S = VIH)(1)
Waveform of BUSY Arbitration Cycle Controlled by
Address Match Timing(M/S = VIH)(1)
NOTES:
1. All timing is the same for left and right ports. Port “A” may be either the left or right port. Port “B” is the port opposite from “A”.
2. If tAPS is not satisfied, the BUSY signal will be asserted on one side or another but there is no guarantee on which side BUSY will be asserted.
Truth Table III — Example of Semaphore Procurement Sequence(1,2,3)
NOTES:
1. This table denotes a sequence of events for only one of the eight semaphores on the IDT7026.
2. There are eight semaphore flags written to via I/O0 and read from all I/O's (I/O0-I/O15). These eight semaphores are addressed by A0 - A2.
3. CE = VIH, SEM = VIL to access the semaphores. Refer to the semaphore Read/Write Control Truth Table.
