How to use PxCON register on nRF24LE1

[junma]

Hi all,

I am a beginner with nRF24LE1, when I want to code some examples using GPIOs, I find that it's difficult to understand the PxCON register function. Whether I configure one pin to input or output, I just use PxDIR register, without using PxCON register, and the experiment results show everything is ok.

So I wonder what's the function of PxCON and in which circumstances is it necessary? It would be better to show some examples about how to use this register, thanks~

Hope someone can help me about this confusion, thanks in advance!

The PxCON is used for configuring the drive strength on the pin in output mode or for example turn off the input buffer. It's also possible to switch on/off pull up/down resistors on the pins.

So PxDIR set the direction, PxCON can configure some additional features of the pin.
