MOTOROLA
Two of Motorola’s MC145574 S/T transceivers are shown connected to ports 0 and 1. The
frame sync control signal FSC0 is connected to S/T transceiver one, while FSC1 is
connected to transceiver two.
Figure 13-42 shows an example of the IDL bus timing relationship of the S/T transceivers
when in standard IDL2 8-bit mode with a common frame sync.
