NUM_COR register: 0xF08E; note 1
Note
1.
Register 0xF08E indicates the number of corrections performed during the most recently executed
CORRECT_P_SYNDROMES or CORRECT_Q_SYNDROMES command. Note that NUM_COR is only valid after
completion of the CORRECT_P_SYNDROMES or CORRECT_Q_SYNDROMES command, and becomes invalid
upon execution of any other command.
