8.6.2
1. By driving the MODE pin ‘high’ the user chooses Motorola Work Mode, by driving it
2. Moreover, there is a difference between work with Multiplexed Address/Data Bus and
8.6.2.1
In this mode R/W distinguishes between Read and Write interactions, and DS is used for
timing.

Data Sheet
P accesses DELIC by an activation of Address and CS.
‘low’ - Intel/Infineon Work Mode. The pin is sampled by RESET rising edge.
Demultiplexed Address and Data Buses (in Intel/Infineon Mode). In Motorola Mode
Demultiplexed Buses only used. The selection between Multiplexed and
Demultiplexed is done by the manner of use of ALE.
