P7
[1]
I/O P1[18] — General purpose digital input/output pin.
O USB_UP_LED1 — USB port 1 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.
O PWM1[1] — Pulse Width Modulator 1, channel 1 output.
I CAP1[0] — Capture input for Timer 1, channel 0.
