(2) Correction result information
[Functional description]
P[1:0]:
Q[1:0]:
CRC:
MSB
Refer to the CRC bit for MODE = 4 and the Q[1:0] and P[1:0] bits for MODE = 2 as needed.
–
When SZ = 0
When SZ = 1
When A[4:0] = 18H, the following correction result information is output.
Shows the P series error correction state for MODE = 2.
Shows the Q series error correction state for MODE = 2.
Shows the results of CRC checking for MODE = 4.
CRC = 1 means CRC checking was OK.
