Bit 2 – CRCERR CRC Error

This bit is read '1' when the memory CRC monitor detects data corruption.

Bit 1 – CRCZERO CRC Zero

This bit is cleared when a new CRC source is selected.

This bit is set when the CRC generation is complete and the CRC Checksum is zero.

Bit 0 – CRCBUSY CRC Module Busy

When used with an I/O interface (CRCCTRL.CRCSRC=0x1):
  • This bit is cleared by writing a '1' to it
  • This bit is set when the CRC Data Input (CRCDATAIN) register is written
  • Writing a '1' to this bit will clear the CRC Module Busy bit
  • Writing a '0' to this bit has no effect
When used with a DMA channel (CRCCTRL.CRCSRC=0x20..,0x3F):
  • This bit is cleared when the corresponding DMA channel is disabled
  • This bit is set when the corresponding DMA channel is enabled
  • Writing a '1' to this bit has no effect
  • Writing a '0' to this bit has no effect
