Note
Table 4-1:,“List of Connections from MPC821ADS to SED1355” on page 16 shows the
connections between the pins and signals of the MPC821 and the SED1355.
The following table details the connections between the pins and signals of the MPC821
and the SED1355.
Table 4-1: List of Connections from MPC821ADS to SED1355
The interface was designed using a Motorola MPC821 Application Development
System (ADS). The ADS board has 5 volt logic connected to the data bus, so the
interface included two 74F245 octal buffers on D[0:15] between the ADS and the
SED1355. In a true 3 volt system, no buffering is necessary.
