5.3 Operation Timing in Memory Expansion Mode and Microprocessor Mode
As there are a flexible cable and other devices between this product and the target system, I/O timing
will differ from that of the actual MCU. Use the following as a reference when using the emulation pod.
(1) The output signal (address, RD*, WR*, etc.) of the evaluation MCU mounted on this product
is output delayed by about 4 ns.
(2) It takes longer time to setup the data than actual MCU by approx. 8 ns.
(1) Timing Requirements
Tables 5.2 and 5.3 list the timing requirements.
