Port I/O Characteristics - Renesas MCU Board for 4513/4514 Group MCUs M34514T-MCU User Manual

5.7 Port I/O Characteristics

With the M34514T-MCU, port I/O characteristics are different from actual MCUs because there is
an emulation circuit in ports P0, P1, P2 and D0 to D5. Table 5.2 lists port I/O characteristics of the
M34514T-MCU.
