Hi Jingcheng,

The '<X>_<Y>' of the modes fields that you circled for UART are:

x = baud rate

y = TTL voltage level, i.e 3.3 or 1.8V

Hi Jingcheng,

For GPIO modes please use the GPMC peripheral.

HI Colin

For UART, I only used the RX/TX two pins , CTS/RTS is not used， So the IO utilization is 50% ? is it correct?

Hi Jingcheng,

if you are using the UARTs constantly without stopping then 100% would be appropriate. If you are using the peripheral one out of 10 minutes, then 10% would be appropriate.

The %Utilization that you choose should be an estimate based on how often the peripheral is used.

Colin
