13.5.2. Non-multiplexed Configuration
In Non-multiplexed mode, the Data Bus and the Address Bus pins are not shared. An example of a
Non-multiplexed Configuration is shown in Figure 13.3. See
page 124
13.6. Memory Mode Selection
The external data memory space can be configured in one of four modes, shown in Figure 13.4, based on
the EMIF Mode bits in the EMI0CF register (SFR Definition 13.2). These modes are summarized below.
More information about the different modes can be found in
