D+/D- I/O pins of the USB on-chip transceiver.
Connect these pins to the D+/D- pin of the USB bus.
USB cable connection monitor pin.
Connect this pin to VBUS of the USB bus.
1.5 k Ω pull-up resistor control signal for USB D+ signal.
USB power supply pin.
Reference voltage input pin to A/D converter.
Analog input pins to A/D converter.
AD external trigger input pin.
Comparator B analog voltage input pins.
Comparator B reference voltage input pins.
CMOS I/O ports. Each port has an I/O select direction
register, allowing each pin in the port to be directed for input
or output individually.
Any port set to input can be set to use a pull-up resistor or not
by a program.
