This page list miscellaneous signals that does not constitute an interface.

Internal DAC

Two sets of differential DAC signals are routed directly from the daughter board to the audio connector. These signals are

SignalDescription
DAC0DAC 0 positive signal
DAC0NDAC 0 negative signal
DAC1DAC 1 positive signal
DAC1NDAC 1 negative signal

Refer the help files of your daughter board to learn how these signals are used on your daughter board.

Reset

STK1000 share a common reset net labelled RESET_N. The reset is active low.

The reset signal will be low when power is applied to the system or when the reset switch is pushed. External Watch Dog timer (RTC_WDTEXT)

The RTC_WDTEXT signal on the PCI style expansion connector allows you to transmit a watch dog timer interrupt signal from custom expansion boards to the AVR32 processor.

Refer the help files of your daughter board to se if this this signal is used on your daughter board.
