Specifications

 iSYSTEM, February 2003 7/8
limited number of Flash erase cycles in the microcontroler (up to 100) it is recommended to use
external flash memory for development process. This memory can be used together with the boot
code for power on initialization.
Programming the Flash memory
winIDEA allows you to load code directly into internal or external Flash memory. You have to
set memory map in your code accordingly with the target configuration. Demo software has the
examples configured for both cases. Load the projects into winIDEA and go to the menu
FLASH>Program and push the Start button. This will download the code directly to Flash
memory. For more information see the winIDEA users manual.
Settings and options
The EVB-56x supports the MPU in the extended chip mode only. Boot can be done using either
external either internal Flash. The device is selected with the jumper FLEN (Flash enable). After
the hard reset the MPU samples the PO configuration and starts the boot process accordingly to
the settings.

The development tool can be connected to the board through two debug ports – BDM and Nexus.
Only one can be selected at time. Port selection is done automatically with the proper signaling.
No manual settings are necessarily.
JTAG Port
JTAG is primarily used for the manufacturing testing and is by default disabled. (JTAG enable
and DBPC are low). Port can be enabled with jumper wires on the cable connector. Hard reset is
needed for the initialization. Signal JTAG compliance on EVB565 must be high.
