How to connect power amplifier for nRF52832

[John Chinnick]

Since the nRF52 does not have the VDD_PA signal that the nRF51 has, what is the recommended method for connecting an external power amplifier that needs TX and RX enable signals?

@John Chinnick: What about using FORK on the PPI channels that do the task radio start and on the event that use the event radio ended(Or use your own PPI channel) and use those FORK or PPI channel to trigger tasks on GPIOTE ?

You now can have 2 GPIOTE tasks to SET and CLR on same pin.

I was thinking this might be a solution. I wanted to confirm that the application has access to the radio PPI channels when the softdevice is active. I was also wondering if there were other options to consider.
