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. Whether VBUS is
connected or disconnected can be detected during operation
as a function.
VBUS (5 V) supply enable signal for external power supply
chip.
External overcurrent detection signal should be connected to
these pins. VBUS comparator signals should be connected
to these pins when the USB host power supply chip is
connected.
1.5 k Ω pull-up resistor control signal for USB D+ signal when
operating as a function controller.
USB power supply pin.
15 k Ω pull-down resistor control signals for USB D+ and D-
signals when operating as a host.
ID input signal for microAB connector should be connected
when operating on OTG.
Low-power control signal for external power supply (OTG)
chip. Connect this pin to the OTG power supply IC to be
connected externally.
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.
