1. Data in SPIDRH is lost in this case.
2. SPIDRH can be read repeatedly without any effect on SPIF. SPIF Flag is cleared only by the read
1. Any write to SPIDRH or SPIDRL with SPTEF == 0 is effectively ignored.
2. Data in SPIDRH is undefined in this case.
3. SPIDRH can be written repeatedly without any effect on SPTEF. SPTEF Flag is cleared only by
