• ENABLE: CRC Enable
• COMPARE: CRC Compare
If set to one, this bit indicates that the CRCCU DMA will compare the CRC computed on the data stream with the value
stored in the TRC_RC reference register. If a mismatch occurs, the ERRISR bit in the CRCCU_ISR register is set.
• PTYPE: Primitive Polynomial
• DIVIDER: Request Divider
CRCCU DMA performs successive transfers. It is possible to reduce the bandwidth drained by the CRCCU DMA by pro-
gramming the DIVIDER field. The transfer request frequency is divided by 2^(DIVIDER+1).
