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.
