Figure 12 - GCI Timing at 2.048 Mb/s and High Speed Serial Interface at
4.096 Mb/s or 8.192 Mb/s, when WFPS pin = 0
Figure 13 - WFP Bus Timing for High Speed Serial Interface (8.192Mb/s), when WFPS pin = 1
Note:
1. High Impedance is measured by pulling to the appropriate rail with R
L
, with timing corrected to cancel time taken to discharge C
