PWM Output
1-Wire bus. Requires an external pull-up resistor. The recommended
GPIO3[14] resistor is specified by the generic 1-Wire device used in a given
system.

SD Data bidirectional signals—If the system designer does not want
GPIO2[25] to make use of the internal pull-up, via the Pull-up enable register, a
50 K–69 K external pull up resistor must be added.
