Notes 1. Since 3-wire CSI and UART are used as alternate-function pins, they must be assigned to either of the

functions for use.

2. The LIN-bus supporting UART pins can be changed to the UART pins (pin numbers 47 and 48).

3. The LIN-bus supporting UART pins can be changed to the 3-wire CSI/UART pins (pin numbers 50 and 51).

4. The values in parentheses are the number of signal outputs when 8com is used.
