Generally speaking,AHBis internal to the ARM core processor and not
something the software needs to deal with. Some processors do allow a level
of manipulation of things, mostly to enable or disable individual devices
and occasionally to set the processor permission level required to access
the device. You will need to read the documentation for the specific
processor you are using for more details.

Hi all,
I need detail information on Por(Power on reset) andAHB
Configuration.As far my information The power-on reset (PoR) is an
electronic device incorporated into the integrated circuit that
detects the power applied to the chip and generates a reset impulse
that goes to the entire circuit placing it into a known state.
AnAHBis a Advanced High-Performance Bus, System bus connecting ARM
cores to peripheral circuits , I/Os , memory and IPs.
All this is H/w related.Is there any software part or drivers attached
to POR orAHB?Do we need to wite any code for proper functiong of POR
andAHB?
