Timer0 and Timer2 are 8 Bit Timers, Timer0 has special uses too and therefore we'll avoid using it.
The timer driver only supports the four 16-bit timers (Timer1, Timer3, Timer4, Timer5), so those are the only ones we can use here.

UART configuration
The UART devices have fixed pin mappings, so all we need to do, is to specify which devices we would like to use and their corresponding RX interrupts.
See the reference manual for the fixed pin mapping.

SPI configuration
The atmega1281 has only one hardware SPI with fixed pin configuration, so all we can do here, is to enable or disable it...
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
