Notes:
1. Conguration must be delayed until the INIT pins of all daisy-chained FPGAs are High.
2. The time from the end of WS to CCLK cycle for the new byte of data depends on the completion of previous byte
processing and the phase of the internal timing generator for CCLK.
3. CCLK and DOUT timing is tested in slave mode.
4. TBUSY indicates that the double-buffered parallel-to-serial converter is not yet ready to receive new data. The shortest
TBUSY occurs when a byte is loaded into an empty parallel-to-serial converter. The longest TBUSY occurs when a new word
is loaded into the input register before the second-level buffer has started shifting out data
This timing diagram shows very relaxed requirements. Data need not be held beyond the rising edge of WS.RDY/BUSY will
go active within 60 ns after the end of WS. A new write may be asserted immediately after RDY/BUSY goes Low, but write
may not be terminated until RDY/BUSY has been High for one CCLK period.
