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.
