I/O P0[12] — General purpose digital input/output pin.
O USB_PPWR2
— Port Power enable signal for USB port 2.
I/O MISO1 — Master In Slave Out for SSP1.

R2
[2]
I/O P0[13] — General purpose digital input/output pin.
O USB_UP_LED2 — USB port 2 GoodLink LED indicator. It is LOW when
device is configured (non-control endpoints enabled), or when host is
enabled and has detected a device on the bus. It is HIGH when the
device is not configured, or when host is enabled and has not detected a
device on the bus, or during global suspend. It transitions between LOW
and HIGH (flashes) when host is enabled and detects activity on the bus.
I/O MOSI1 — Master Out Slave In for SSP1.
I AD0[7] — A/D converter 0, input 7.
