Rising CLK edge to falling CLK edge
Falling CLK edge to CLK rising edge
Falling CLK edge for last data bit (DI)
to falling CS edge
Rising CS edge to next rising CLK edge
Data valid to first rising CLK
edge after CS = high
Rising CLK edge to end of data valid
Rising CLK edge to D0 = low
Rising CS edge to D0 becoming high
low impedance (active output)
Rising CLK edge to D0 = high
Rising PROG edge to next rising
