Baud Rate select -
used to configure 9600 or software selected (default=115K ) baudrate. If the switch is
OFF, the stored baudrate setting will be used. When the switch is in the ON position, the baudrate will be set
to 9600 regardless of the software setting.
NOTE: for the purpose of configuration above, the swithes/IO pins are sampled ONLY at power up time,
(during the first 500milliseconds) so they can be used for other functions once the device is in operation.
The exception is the factory reset switch/PIO, which once enabled, can be toggled at any time after powerup,
a total of 3 transitions will cause the factory reset to occur.
