Translation - Japanese: PSoC® 3 / PSoC 5LP USBIO を GPIO として使用する - KBA92716 - Community Translated (JA)
How can I use USBIOs (D+: P15 and D-: P15) for GPIO functionality?
USBIOs only support the drive modes ‘Open Drain, Drives Low' and 'Strong Drive'. If your GPIO is any of these drive modes, then you will be able to assign USBIOs (D+: P15 and D-: P15) to your GPIO in the PSoC Creator™ cydwr Pins tab. If the drive mode of the GPIO is different from these specified drive modes, the pins P15, P15 cannot be assigned to the GPIO.
