nRF52832 SDK15.3.0 How to use GPIOTE & PPI

[Glory]

Hello.

nRF52 A custom board is being developed.

I want to use Crypto Chip Pulse to encrypt.

Pulse_Out of Crypto Chip is connected to P028/AIN4.

In order to measure Pulse, the count between Rising edge to Rising edge must be calculated.

I think we need to use GPIOTE and PPI. Please advise.
