13.4.2 CRCSEED Register (Offset = 410h) [reset = 0h]
CRC SEED/Context (CRCSEED)
The CRC SEED/Context (CRCSEED) register is initially written with one of the following three values depending on the encoding of the INIT field in the CRCCTRL register:
- The context value written to the CRCSEED register. This encoding is for SEED values from a previous CRC calculation or a specific protocol. (INIT = 0x0)
- 0x00000000 (INIT = 0x2)
- 0x11111111 (INIT = 0x3)
CRCSEED is shown in Figure 13-2 and described in Table 13-6.
