Description
High: external On/Off signal is Low (in OFF
state) (default)
Low: external On/Off signal is High (in ON
state)
Note: GPIO58 must be low in order for
device to power off.
High: External I/O1 is low (ground)
Low: External I/O1 is high
Default is external low.
High: Enables internal pull-up to 3.3V
(default)
Low: Disables internal pull-up
High: External I/O2 is low (ground)
Low: External I/O2 is high
Default is external low.
High: Enables internal pull-up to 3.3V
Low: Disables internal pull-up (default)
ADC with 15 bits of resolution (FX30 3G)
ADC with 15 bits of resolution (FX30 Cat-1/
Cat-M)
High: External I/O3 is low (ground)
Low: External 1/O3 is high
Default is external low.
High: Enables internal pull-up to Vin
Low: Disables internal pull-up (Default)
High: Output transmitter ON—clamps
external IO3 to ground
Low: Output transmitter OFF—IO3 floats
(can be used as input)
Default is external low.
High: External Push button is released
(default)
Low: External push-button is being pushed
