Hai friends,
I am using MC9S12E128 controller with CodeWarrior V4.5,
Cyclone pro debugger and powered with 3.3V . Configuration used is
16Mhz bus frequncy with PLL activated,and Normal Expanded wide mode
with 0x4000 to 0x7fff as external address range. The multiplexed A/D
bus interacts with CPLD.I am facing two problems:
1) Non initialization of global variables at power-on and
2) Unable to properly use external access A/D bus due
to local variables.(Access to CPLD is fine when local
variables are shifted to static scope)
May i know the reason for above problems and dependency of
stack operation for local variables with External Bus Interface module.
Thanks in advance,
cheers,
Srinivas P.
