SF0DWR is an 8-bit (byte) or 16-bit (word) special function register (SFR) used to hold transmitted data.
Write access to this register should be:
8-bit write access to SF0DWRL for 8-bit transmission (SF0SIZ=0)
16-bit write access to SF0DWR for 16-bit transmission (SF0SIZ=1)
Operation is not guaranteed for other accesses.
