I am using MC9S12NE64. We have got external RAM in our design to store data and an extrernal crystal clock of 25MHz.
I want to know what is the maximum frequency we can operate NE64 processor, when using expanded mode operation.
Processor datasheet says that operating frequency is 32 MHz in expanded bus mode and 50MHz for single chip mode.
Can I run the processor at 50MHz while being in expanded bus mode ? Is it allowed?
What impact this might have on the processor?
