Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary? The CSP47 reference design does not show any passives on the same pin (why?).
Since there is an internal weak pullup, can we just leave it floating if unused or directly connect it to an external GPIO?
Thanks
