Jitter check
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 retired 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.
