Info rmation
DYB to a 1 protects the sector from programs or erases. Since this is a volatile
bit, removing power or resetting the device will clear the DYBs. The bank address
is latched when the command is written.
Command
The programming of either the PPB or DYB for a given sector or sector group can
be verified by writing a Sector Protection Status command to the device.
Note that there is no single command to independently verify the programming
of a DYB for a given sector group.
Command Definitions Tables
Legend:
BA = Address of bank switching to autoselect mode, bypass mode, or erase operation. Determined by Amax:A19.
PA = Program Address (Amax:A0). Addresses latch on falling edge of WE# or CE1#/CE2# pulse, whichever happens
later.
PD = Program Data (DQ15:DQ0) written to location PA. Data latches on rising edge of WE# or CE1#/CE2# pulse,
whichever happens first.
RA = Read Address (Amax:A0).
RD = Read Data (DQ15:DQ0) from location RA.
SA = Sector Address (Amax:A12) for verifying (in autoselect mode) or erasing.
WD = Write Data. See “Configuration Register” definition for specific write data. Data latched on rising edge of WE#.
X = Don’t care
Notes:
1. See Table 1 for description of bus operations. 2. All values are in hexadecimal.
3. Shaded cells in table denote read cycles. All other cycles are write operations.
