SPI Interrupt Requests. If unused, this pin should be tied to ground directly or through a 4.7K resistor. Atmel Test Pins. Only utilized during manufacturing test. To optimize power savings and improve noise immunity, these ATest pins should be biased to VCC or GND as follows: TSSOP Pin 21 / QFN Pin 19 TSSOP Pin 23 / QFN Pin 21 TSSOP Pin 26 / QFN Pin 24 No Connect Pins. The AT97SC3205T TSSOP package has additional pins which are no connects and can be tied to GND, VCC, or left floating at the customers discretion: NC – TSSOP Pin 5 NC – TSSOP Pin 12 NC – TSSOP Pin 13 NC – TSSOP Pin 14 NC –...
