The Atomthreads port uses Timer 1 to drive the system tick. If you wish
to use some other timer then you may do so by modifying atomport.c.
Note that the build scripts make no assumptions about the RAM and program
space available on your platform, partly because you may have external RAM
over and above the ATmega device's internal SRAM. You must, therefore,
ensure that you have sufficient RAM and program space available for the
applications that you build. This information can be obtained by passing
the application ELF filename to the avr-size utility.
