 * The timer driver only supports the four 16-bit timers (Timer1, Timer3,

 * The fixed pins used, are:
 * MOSI - PB2 (waspmote SPI-UART socket MOSI)
 * MISO - PB3 (waspmote SPI-UART socket MISO)
 * SCK  - PB1 (waspmote SPI-UART socket SCK)
 * SS   - PB0 (waspmote SD Card Chip Select) -> this pin is configured as output, but not used
