Can you use all 3 SPI master ports and 2 UART ports at the same time?

Hi,

I've been looking at the peripheral IDs in the instantiation table of the datasheet. 

Is there any problem with using all 3 SPI master ports and both UART ports at the same time? They do not have peripheral ID conflicts. 

If we need to we can consolidate down to two SPI ports, but I think this design will be cleaner and less prone to weird conflicts if I can isolate devices on their own buses as much as possible.

Thanks!

Hello,

As far as I can tell, there is no reason why you can't use all of these concurrently. On the nRF52840, the SPI only shares resources with I2C, so that you can't use e.g. SPI0 and I2C0 (TWI0). But you can use UART0, UART1, and SPI0, SPI1 and SPI2. No problem.

Best regards,

Edvin
