I need to communicate to a Digital to Analog converter through the SPI Port at a fast rate (1024 times in 20ms = every 19 uS), with no interruptions.I was thinking of using the XGATE to perform this task (and this task only).
I'm thinking of using MC9S12XEP100CAL, and my questions are the following::::
1. Can I access the SPI ports from the XGATE?
2. All the XGATE needs to do is read from a pre-defined Array of  and write the values at the same rate to the Digital to Analog though SPI. How fast can the XGATE perform this task.
