Notes:
1. Peripheral Synchronous mode can be considered Slave Parallel mode. An external CCLK provides timing, clocking in the
rst data byte on the second rising edge of CCLK after INIT goes High. Subsequent data bytes are clocked in on every
eighth consecutive rising edge of CCLK.
2. The RDY/BUSY line goes High for one CCLK period after data has been clocked in, although synchronous operation does
not require such a response.
3. The pin name RDY/BUSY is a misnomer. In Synchronous Peripheral mode this is really an ACKNOWLEDGE signal.
4. Note that data starts to shift out serially on the DOUT pin 0.5 CCLK periods after it was loaded in parallel. Therefore,
additional CCLK pulses are clearly required after the last byte has been loaded.
