A temperature sensor MCP9800 is connected to the SAM3U4E TWI bus. This device also features an
open-drain output ALERT pin. The device outputs an alert signal when the ambient temperature goes
beyond the user-programmed temperature limit.
Note that the 0-Ohm resistors R15 and R16 have been implemented to offer a disconnection possibility
(freeing these dedicated PIO lines for other custom usage).
The SAM3U-EK has an MMC/MMCPlus high-speed 8-bit multimedia interface. This interface is used as
a 4/8-bit interface, connected to an 8-bit SD/MMC card slot with card detection.
