Description
7
GP17_RESON R/W VSB3V Set to 1, turn on the GPIO17 internal pull-up resistor.
6
GP16_RESON R/W VSB3V Set to 1, turn on the GPIO16 internal pull-up resistor.
5
GP15_RESON R/W VSB3V Set to 1, turn on the GPIO15 internal pull-up resistor.
4
GP14_RESON R/W VSB3V Set to 1, turn on the GPIO14 internal pull-up resistor.
