Figure 4-1: Typical Implementation of MCF5307 to S1D13704 Interface
The S1D13704 is interfaced to the MCF5307 with a minimal amount of glue logic. One
inverter is required to change the polarity of the WAIT# signal, which is an active low
signal to insert wait states in the bus cycle, while the MCF5307’s Transfer Acknowledge
signal (TA) is an active low signal to end the current bus cycle. The inverter is enabled by
CS# so that TA is not driven by the S1D13704 during non-S1D13704 bus cycles. A single
resistor is used to speed up the rise time of the WAIT# (TA) signal when terminating the
bus cycle.
The following diagram shows a typical implementation of the MCF5307 to S1D13704
interface.
