Cyclic Redundancy Check Reset Control.

Cyclic Redundancy Check Reset ControlControls reset state of the Cyclic Redundancy Check (CRC) engine. CRC provides hardware-accelerated error detection for data integrity verification in communication and storage applications.

CRC Functions:

• High-speed CRC calculation for data integrity verification
• Multiple CRC polynomial support (CRC-16, CRC-32, custom)
• Programmable seed values and bit/byte reversal options
• DMA integration for automatic data stream processing

註

Reset Effects:

• CRC calculation in progress is terminated
• Accumulator and result registers cleared

• Polynomial and configuration registers reset to defaults

  Integrity Check:

  // Initialize CRC for data verification
  reset_ctrl.assert_reset(Control::CRC);
  reset_ctrl.release_reset(Control::CRC);
  crc_configure_polynomial(CRC32_IEEE);
  uint32_t checksum = crc_calculate(data_buffer, length);
