Preliminary
5.8: COMET/PAKIT Syndrome Register
This register holds the syndrome bits that can be used to isolate the data or check bit in error when ECC is
used. When parity is used, this register indicates which of the four bytes of the memory bus had a parity error.

When using ECC, a single bit error can be identified by matching the contents of this regis-
ter to the corresponding bit in the table below. When using parity, only bits 3-0 are valid and
are interpreted as follows:
0000
0001
0010
0100
1000

Reserved
No parity error
Parity error on bits 7-0
Parity error on bits 15-8
Parity error on bits 23-16
Parity error on bits 31-24
Reserved
