RESET
I
Master Reset signal. Internally pulled up to 3.3V via a 10K resistor. An active Low
pulse greater than 2 micro-seconds will reset the module. If the module needs
to be reset externally, only use open collector type circuits. This pin is not driven
low by any internal conditions. The host should control this pin via one of its
port pins using an open collector/drain arrangement.
