Reset command
The reset command provides a means of stopping execution of the
erase or program command safely. If the user inputs command code
FF
in the second cycle after inputting the erase or program com-
16
mand in the first cycle and again input command code FF
in the
16
third cycle, the erase or program command is disabled (i.e., reset),
and the M37753FFCFP and the M37753FFCHP are placed in the
read mode. If the reset command is executed, the contents of the
memory does not change.
Device identification code command
By inputting command code 90
in the first cycle, the user can read
16
out the device identification code. The command code is latched into
___
the internal command latch at the rising edge of the WE input. At this
time, the user can read out manufacture’s code 1C
(i.e.,
16
MITSUBISHI) by inputting 0000
to the address input pins in the
16
second cycle; the user can read out device code D0
(i. e., 1M-bit
16
flash memory) by inputting 0001
.
16
These command and data codes are input/output at the same timing
as for read.
