4.9 Sector Protect (By Command Input)
This command performs sector protect.
By applying V
ID
to /RESET and writing 60H to any address, the device enters the sector protect or unprotect mode.
Sector protect is started by inputting the sector address of the sector to be protected to A13 to A19, inputting V
IL
to
A0 and A6, inputting V
IH
to A1, and writing 60H. After a timeout of 100
μ
s, sector protect is completed.
Next, with the sector address input to A13 to A19, the device enters the sector protect verify mode by inputting V
IL
to
A0 and A6, V
IH
to A1, and writing 40H. When read is performed in this state, the sector protect verify result is output
to I/O0. If "1" is output to I/O0, the verified sector is protected. If "1" was not output to I/O0, sector protect failed, so
perform sector protect again.
Sector protect can also be performed by inputting V
ID
to A9 and /OE. For details, see section
3.6 Sector Protect
.
