5.6 Port I/O Timing
(1) Port input timing
Port input timings are the same as with the actual MCUs.
(2) Port output timing
When using the M34514T-MCU, output timings are different from those of the actual MCUs for
the following ports that are configured with port emulation circuits:
•Ports P00 to P03
•Ports P10 to P13
•Ports D0 to D5
With the actual MCUs, changes occur at the beginning of the T3 state of an output instruction.
With the M34514T-MCU, changes occur at the beginning of the T2 state of the next output
instruction. Figure 5.2 shows the port output timings of the actual MCUs and M34514T-MCU.
For the other ports, the output timings are the same as with the actual MCUs.
