[5]

I/O

P0[13] — General purpose digital input/output pin.

USB_UP_LED2 — USB port 2 GoodLink LED indicator. It is

LOW when device is configured (non-control endpoints

enabled). It is HIGH when the device is not configured or during

global suspend.

I/O

SSP1_MOSI — Master Out Slave In for SSP1.

ADC0_IN[7] — A/D converter 0, input 7. When configured as an

ADC input, the digital function of the pin must be disabled.
