The frame ends when NSS goes high. The next frame must start with an address byte. The SINGLE access mode is
therefore a special case of FIFO / BURST mode with only 1 data byte transferred.
During the write access the byte transferred from the slave to the master on the MISO line is the value of the written
register before the write operation.
