12.3 Register Map
Table 12-3 on page 949 lists the CRC Module registers. The offset listed is a hexadecimal increment
to the register's address, relative to the base address 0x4403.0000.

12.4 CRC Module Register Descriptions
This section lists and describes the CRC registers, in numerical order by address offset.
Note: The CRC module can only be accessed through privileged mode. If the µDMA is used for
CRC transfers, then the µDMA's DMA Channel Control (DMACHCTL) register also needs
to be programmed to allow for privileged accesses.
