Jitter check.
Jitter rate is measured and displayed.
Measurement is repeatedly done in
the cycle of one second. Read error
counter starts from zero upon mode
setting.
When target block data failed to be
read out, the counter advances by one
increment. When the failure is caused
by minor error, it may be corrected
when retried to enable successful
reading.
In this case, the counter advances by
one. When the error persists even
after retry, the counter may jump by
two or more.
