Writing a one to this bit will enable the correction to be done after the Partial Syndrome process and allow interrupt to be sent to
CPU.
Writing a zero to this bit will stop the correction after the Partial Syndrome process.
1: The correction will continue after the Partial Syndrome process.
0: The correction will stop after the Partial Syndrome process.
Writing a one to this bit will stop the computation.
Writing a zero to this bit will allow the computation as soon as read/write command to the NAND Flash or the SmartMedia
detected.
1: The computation will stop until a zero is written to this bit.
0: The computation is allowed.
