Error Magnitude 2. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.
Error Magnitude 3. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.
Error Magnitude 4. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.
Error Magnitude 5. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.
Error Magnitude 6. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.
Error Magnitude 7. This output indicates which bit of the current symbol output on Q7-Q0 has been
corrected when LOC is HIGH. This output is indeterminate and should be ignored when LOC is low.

92 DEC_P4
Decoder parity input bit 1. This determines the value of (P) which is the maximum of check bytes
that the device will use in correction before flagging the block as uncorrectable. Normally set to the
Input
# of check bytes (R). P4 is the most significant bits.
Decoder parity input bit 2. This determines the value of (P) which is the maximum of check bytes
that the device will use in correction before flagging the block as uncorrectable. Normally set to the #
Input
of check bytes (R). P4 is the most significant bits.
Decoder parity input bit 3. This determines the value of (P) which is the maximum of check bytes
that the device will use in correction before flagging the block as uncorrectable. Normally set to the
Input
# of check bytes (R). P4 is the most significant bits.
Decoder parity input bit 4. This determines the value of (P) which is the maximum of check bytes
that the device will use in correction before flagging the block as uncorrectable. Normally set to the #
Input
of check bytes (R). P4 is the most significant bits.
