The pin configured to provide the "General purpose output" function is set as
Output / Low, if the parameter <gpio_out_val> of AT+UGPIOW command is set to 0
o
Output / High, if the parameter <gpio_out_val> of AT+UGPIOW command is set to 1
o
 Pad 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 "Pad 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 "Pad disabled" function is set as
Tri-state with an internal active pull-down enabled
