2.8 WRITE All (WRAL)
The entire chip will be written with the data specified in
that command. The WRAL cycle is completely self-
timed and commences after the last data bit (D0) has
been clocked in. WRAL takes 15 ms maximum.
Note:
The WRAL does not include an automatic
ERASE cycle for the chip. Therefore, the
WRAL instruction must be preceded by an
ERAL instruction and the chip must be in
the EWEN status in both cases. The
WRAL instruction is used for testing and/or
device initialization.
