What speeds do the TI processors allow the SPI bus to run? For example, if the processor is 220MHz, is SPI limites to 110MHz (divide by 2), 55MHz (divide by 4) or less?
Is there a general rule for TI micros speed vs SPI speed?
We are looking at using the SPI bus to oversample a slower (24MHz) signal on the bus and recreate it with firmware. 4x oversampling would be good, so I am wondering which MCU speed I would need.
Thanks,
