54 / 149 page  54 S29PL129J for MCP S29PL129J_MCP_00_A0 June 4, 2004 Advance 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. Table 12.
