
Pin disabled
:
All the GPIOs can be configured in tri-state with an internal active pull-down enabled, as a not used pin,
setting the parameter <gpio_mode> of +UGPIOC AT command to 255.
The “Pin disabled” mode can be provided on more than one pin per time: it is possible to simultaneously set
the same mode on another pin (also on all the GPIOs).
The pin configured to provide the “Pin disabled” function is set as
o
Tri-state with an internal active pull-down enabled
