Yeah .... I don't think it is all that rare, or a case of poor
design of hardware. More like another Microchip gotcha.

How often do you hang a cap straight on a port pin for noise
filtering, or drive an RC on output? Standard small values 1K
and 1 nF gives a 1 usec time constant, as do 10K and 100 pF.

And if you actually do want noise-filtering, then 1 usec ~ 160khz
is not gonna do such a great filter job --> caught by the M.gotcha.
