question about KEA128 Setup registers

vegetarian1 — Thu, 14 Mar 2019 09:49:52 GMT

At beginning, system would run __thumb_startup which is used for initialization of PC. __init_registers() would be invoked in it, and the FDIVLD field of Flash Clock Divider Register for KEA128 is set at the same time in my project. It means that register has been written since the last reset. Obviously, it has nothing to do with my code, because it is too earlier. I don't know what __init_registers() has done. But it doesn't happen in another project. How to avoid this problem?
Thank you for your attention.

Hello Mike,

You can find the definition of " __init_registers()" under CodeWarrior install:

CW MCU v11.0\MCU\ARM_EABI_Support\ewl\EWL_Runtime\Runtime_ARM\Source\__arm_eabi_init.c

Have a great day,
TIC
