Have a look at chapter 35 for UARTE and chapter 50 of the product specification for UART.

Thank you very much for your reply！I read the product specification ,but i don't know much about the peripheral UARTE.The nRF52832 has one physical UART just like the picture below

In my design,the nRF52832 is used as a MCU, the peripheral circuit contains two UART passthrough like the picture below

When i made this design, It just used one UART when the system worked. But now, i want to use two UART at the same time, so i have to build another UART by simulation. Can you provide me with relevant examples or documents？

The nrf52832 has one peripheral UARTE and one UART, which mostly differ in the capability to use DMA. So, before you start bit banging, you should read the product specification.

best regards,
