Clocked Synchronous Mode:
•
Data length: 8 bits
•
Receive error detection: Overrun errors
Smart Card Interface:
•
An error signal can be automatically transmitted on detection of a parity error during reception.
•
Data can be automatically re-transmitted on detection of an error signal during transmission.
•
Both direct convention and inverse convention are supported.
Figure 15.1 shows a block diagram of SCI.
