Figures 60 and 61 are example timing diagrams of a register read and a register write to the Dual ProSLIC using
the GCI. As noted in Figure 59, the transmitter should always anticipate the acknowledgement of the receiver for
correct communication with the Dual ProSLIC. Devices that do not accept this “best case” timing scenario will
not be able to communicate with the Dual ProSLIC.
