TC1775
Preliminary
Serial Interfaces
The TC1775 includes six serial peripheral interface units:
– Two Asynchronous/Synchronous Serial Interfaces (ASC0 and ASC1)
– Two High-Speed Synchronous Serial Interfaces (SSC0 and SSC1)
– One TwinCAN Interface
– One J1850 Serial Data Link Interface (SDLM)
Asynchronous/Synchronous Serial Interfaces
Figure 5 shows a global view of the functional blocks of the two Asynchronous/
Synchronous Serial interfaces ASC0 and ASC1.
