Table 219: Hash Key Register 0 (Offset: 0x670)
Bit Field Description Init Access
31:24 Hash_key[7:0] The first byte of the hash_key. Bit31 is the first bit of the hash_key. It’s
the big endian format.
0RW
23:16 Hash_key[15:8] The 2nd byte of the hash_key. The bits are in the big endian format 0 RW
15:8 Hash_key[23:16] The 3rd byte of the hash_key. The bits are in the big endian format 0 RW
7:0 Hash_key[31:24] The 4th byte of the hash_key. The bits are in the big endian format 0 RW
