Hello, I'm working on an application which includes CAN/SPI/CAPSENSE. What I'm trying to make sure is that would any of these functions go wrong if there are no ECO(XTAL) sync'd with PSOC 4100. I'm pretty getting close to the point that CAPSENSE/SPI would work fine in XTAL-less environment. What nags me now is CAN.
1. Did anyone experience flaws in CAN without XTAL even in high/low temp situations?
and one more thing.
2. Datasheet very roughly advises me that any XTAL freq ranging from 4~32MHz would be OKAY for PSOC 4100. Does that mean it would work with fractional frequencies(i.e 27.12MHz)?
1) Please refer to Section 2.2 Configuring CAN component in hardware of Control Area Network (CAN) Protocol Troubleshooting Guide for PSoC® - KBA224456
2) Yes, you could use fractional frequencies as well.
