Synchronous acceptor trigger mode
Use the synchronous acceptor trigger mode (SynchronousA) with the SynchronousM trigger mode.
The roles of the internal and external drives are reversed in the SynchronousA trigger mode.
Figure 72: SynchronousA input trigger
Input characteristics
:
•
The falling edge is detected as the external drive pulses the line low, and the internal drive latches the
line low
Figure 73: SynchronousA output trigger
Output characteristics
:
•
The physical line state does not change until all drives (internal and external) release the line.
Synchronous trigger mode
The synchronous trigger mode is a combination of SynchronousA and SynchronousM trigger modes.
The SynchronousA and SynchronousM trigger modes provide additional flexibility.
