Subject: Some Chipcon devices have a resistor and capacitor on the !RST line.
X-Git-Url: http://git.rot13.org/?p=goodfet;a=commitdiff_plain;h=96bf694c533026d571e3fa567edc450ae8a1e24a

Some Chipcon devices have a resistor and capacitor on the !RST line.
This slows down the init sequence, allowing stubborn devices to initialize.
