■ Setting the Memory Connective Switches
These switches can be used to disconnect address lines disabled by the memory capacity switching
function from buffers and using them as user resources instead when the external-memory emulation
function is used. Even when the external-memory emulation function is not used, the switches can
be used to disconnect those address lines from buffers to reduce the load on the address lines used as
user resources.
Figure 5.4-3 shows the factor settings of the switches; Table 5.4-2 lists the elements of the switches
and their respective signal conductors and evaluation MCU’s pin numbers.

* : The user resources corresponding to the above pin numbers are different depending on the eval-
uation MCU used.
For details, refer to the hardware manual for the evaluation MCU to be used or “APPENDIX
User Interface Specifications”.
