UART Configuration

[RakeshHegden]

Hi All,

I am Using the NRF52840 DK Device for my application development 

I want 2 UARTS for my application 

I have used the example -  nRF5_SDK_15.3.0_59ac345\examples\peripheral\serial_uartes\pca10056 in this the Pins are configured 8,6,27,26, In my application board i have used pin 19 and 20 for UART0 and 21,22 for UART1.

Unfortunately other than 8,6,27,26,  none of the pins does these UART functions by changing the pin no 

can somebody explain to me how to configure the pin 19 and 20 for UART0 and 21,22 for UART1?

With Regards,

Rakesh

p0.19-22 is already in use by the QSPI peripheral to connect to the external flash on the DK.

See the DK's hardware description: Connector interface for details.

So I can't able to use the 19 to 22 pins as UARTE? but the datasheet says  the below 

Figure 100: UARTE configuration The GPIOs used for each UART interface can be chosen from any GPIO on the device and are independently configurable. This enables great flexibility in device pinout and the efficient use of board space and signal routing.
