INTEGRATED INPUTS / OUTPUTS
As soon as driver development assistance tools
will be available (Processor Expert), we will
used them intensively to explain how to program
peripheral operation.
TIMERS

DEVELOPMENT METHODOLOGY
- Adapting the configuration of the S12X to
satisfy the end user requirements
- Subcontracting data transfers (DMA like)
to XGATE
