Using XPD_DCDC as a general input

[Aleix]

Hi everyone,

We just had our first boards prototyped and ran into a small issue.
What's called on the datasheet pin functions: XPD_DCDC, I/O, Deep sleep wake-up;GPIO16 has no referenced function "GPIO" on the pin list released as .xls

So, in order to use XPD_DCDC as a general input in the user's firmware, how should we declare the pin instance?

Ie, what in GPIO14 yould be: PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTMS_U,FUNC_GPIO14), how would that be for GPIO16?

Thanks,

Hi,

\ESP8266_NONOS_SDK_v1.5.4\driver_lib\driver\gpio16.c , could it help ?
