NOTES
1. The serial clock rising edge should occur at the centre of the data period for optimum performance. (See Figure 1)
2. Since the GS9020A does not have a parallel clock input, it is not possible to define timing details relative to it. Instead the
GS9020A has a parallel clock output and all timing information is relative to PCLKOUT. The flag port pins (FL[4:0], F_R/W,
S[1:0]) are the only inputs where the timing details are important. The timing requirements are shown in Figure 2.
3. These times are relative to the rising edge of PCLKOUT as shown in Figure 3. Note that the data transitions at the falling
edge of PCLKOUT. T is the parallel clock period in ns.
4. The Host Interface signals, P[7:0], R/W, A/D and CS are asynchronous to the parallel clock.
