Mode
The CMFR provides a program margin read with electrical margin for the
program state. Program margin reads provide sufficient margin to
assure specified data retention. The program margin read is enabled
when SE = 1 and a programming write has occurred. To increase the
access time of the program margin read the off-page access time is 17
clocks instead of the usual 2-clock off-page read access time. The
program margin read and subsequent on-page program verify reads
