A Note on Using
Compact Emulators and MCU Boards
for the 4500 MCU Series

Please take note of the following problem in using the M34519T2-CPE and M34552T2-CPE compact emulators; and the M34519T-MCU and M34524T-MCU MCU boards (used for the 4500 MCU Series):
  • On the initial conditions of ports


  1. Products Concerned

    Notes:
    * For the 4518, 4519, 4583, and 4584 MCU groups
    ** For the 4552, 4553, and 4584 MCU Groups
    ***For the 4524 and 4554 MCU groups


  2. Description
    From reset on through leaving reset to program starts (address 0 in page 0)*, Port (P00-P03, P10-P13, and D0-D5) state is "L" level.

    NOTE:
    * In the M34519T2-CPE, this time period is from reset on through leaving reset to the 124th clock of the XIN input.

    The differences between the actual MCUs and the products concerned in their output levels are shown below.
     From Reset On Through Leaving
    Reset up to Program
    After Program
    Starts
    Actual
    MCUs
    High-impedance High-impedance
    (until setting output
    levels of ports)
    Products
    Concerned
    LOW level High-impedance
    (until setting output
    levels of ports)
    NOTE: This symptom does not appear in the other ports.


  3. Solution
    We are remodeling the products concerned free of charge and will inform you when we start the remodeling later in our tool news.
