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