XGATE Coprocessor
> Peripheral coprocessor performing complex
DMA and data preprocessing features
> Easily programmable in C
> Up to 80 MHz operation
> Low level of interrupt
loading on the main CPU
> Transfers data to or from peripherals,
RAM and Flash without CPU intervention
or CPU wait states
> Able to perform operations on data
(logical, shifts, arithmetic, bit operations)
Memory
> Proven automotive Flash technology
