in the improper sequence will reset the device to the
read mode. Table 4 defines the valid register command
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the
Sector Erase operation is in progress.
COMMAND DEFINITIONS
Device operations are selected by writing specific ad-
dress and data sequences into the command register.

TABLE 4. MX29LV017B COMMAND DEFINITIONS
Notes:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A20=do
not care.
(Refer to table 2)
DDI = Data of Device identifier : C2H for manufacture code, C8H for device code.
X = X can be VIL or VIH
RA=Address of memory location to be read. RD=Data to be read at location RA.
2. PA = Address of memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address of the sector to be erased.
3. For Sector Protect Verify operation:If read out data is 01H, it means the sector has been protected. If read out data
is 00H, it means the sector is still not being protected.
4. Any number of CFI data read cycles are permitted.
5. The reset command is required to return to the read mode when the device is in the automatic select mode or if Q5
goes high.
