How to defer low drive mode and high drive mode

[LeonWu]

Hi team,

My customer is working on design with nRF52832, and they want to know how to defer the low drive mode and high drive mode as below?

Also, shall that be configured by software? What is the setting should be?

Thanks!

Leon

Hi,

 

This is a reference to the field "DRIVE" in register NRF_GPIO->PIN_CNF[n].

Low drive mode is the default configuration when a gpio is configured as output.

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/gpio.html?cp=4_2_0_19_2_9#register.PIN_CNF-0

S0S1 = "low drive" or standard drive

H0H1 = "high drive" for both driving output low and high.

 

Kind regards,

Håkon
