Notes: 1. Configuration must be delayed until INIT pins of all daisy-chained FPGAs are high.
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.
