The value of UART oversampling

[XiaoPing_Yang]

Hi Sir ,

    In the UART configure Tab , there is a parameter  of oversampling . If I set it 12 , that means ,the 12 sample of level must be the same,and congfirm the final level on

the Pin.Is that right?

    Thanks.

Hi xiaopingyang_1543386​,

I hope you are referring to PSoC 4 SCB component of UART. In UART, oversampling factor determines the data rate of transmission:

Data rate = (fSCBCLK / Oversampling value)

Please refer to PSoC 4 Serial Communication Block (SCB) component datasheet Pg 6 Interface data rate configuration section
