Appendix A <Reference> External Device Interface Timings
This section shows setup examples for setting timing conditions of the external system interface as a reference
material used when configuring a system with external devices.
Pay attention to the following precautions when using this material.
The described AC characteristic values of external devices are standard values. They may differ from those of the
devices actually used, so the actual setup values (number of cycles) should be determined by referring the manual or
specification of the device to be used.
It is necessary to set the timing values allowing ample margin according to the load capacitance of the bus and
signal lines, number of devices to be connected, operating temperature range, I/O levels and other conditions. The
number of cycles described in this section is an example and the conditions are not considered.
The values described in "Time" column of the tables are simply calculated by multiplying the number of cycles by
the cycle time. Conditions such as the output delay time of the device, delay due to wiring and load capacitance,
and input setup time are not considered.
The described contents are reference data and cannot be guaranteed to work.
