Details:
The definition of lfuse byte in iotn2313.h is :
#define LFUSE_DEFAULT (FUSE_CKSEL0 & FUSE_CKSEL2 & FUSE_CKSEL3 & FUSE_SUT0 &
FUSE_CKDIV8)
According to the datasheet, this should be :
#define LFUSE_DEFAULT (FUSE_CKSEL0 & FUSE_CKSEL1 & FUSE_CKSEL3 & FUSE_SUT0 &
FUSE_CKDIV8)
This has the effect of setting the default oscillator speed to 4MHz instead
of 8MHz.
