Hi,

Use section 18.10.2 from nRF52832 Product Specification v1.4

Does this mean after I pull P0.21 down to low, it will take time to go high depending on C and R?

Hi,

See this answer: nRF52 minimum reset hold time

The RESET pin must be held low for a minimum of 0.2uS in order to generate a valid reset event.
