3.4
The µP interface may be operated in different modes. This chapter describes how to
configure the DELIC to each mode.
3.4.1
The processor mode is selected by the MODE input pin of the DELIC. "Low" level selects
Infineon/ INTEL mode, "HIGH" level selects Motorola mode.
3.4.2
In both modes, the A-bus and the D-bus are used in parallel. The A-bus should be
connected to the 8 LSBs of AD-bus, coming from the µP, also in multiplexed mode. The
mode is determined according to the ALE input pin. When ALE is permanently driven to
‘1’, the DELIC works in de-multiplexed mode. Otherwise the DELIC works in multiplexed
mode.
The next figure describes the connection of the DELIC to the address and data buses in
the different modes.
Note: Motorola mode is used only with de-multiplexed AD bus. Intel/Infineon mode may

be used with both, multiplexed or de-multiplexed AD bus.
