Peripheral operating requirements and behaviors
1. The DSPI module can operate across the entire operating voltage for the processor, but to run across the full voltage
2. The delay is programmable in SPIx_CTARn[PSSCK] and SPIx_CTARn[CSSCK].
3. The delay is programmable in SPIx_CTARn[PASC] and SPIx_CTARn[ASC].
