Use of USB pins as GPIO in PSoC 3/5
In PSoC 3/5, Can the USB pins be used as GPIOs if they are not being used for USB functionality?
Parts on which they have no USB support, they have P15 and P15 as NC. On those parts, USB pins can not be used for GPIO functionality.
Part which have USB functionality available, P15 and P15, can be used for GPIOs. But only available drive modes for these pins are Strong Drive or Open Drain Drives Low.
