10 / 68 page MBM29PL32TM/BM90/10 10 (Continued) Legend : Address bits A20 to A11 = X = “H” or “L” for all address commands except for Program Address (PA), Sector Address (SA) and Sector Group Address (SGA). Bus operations are defined in “MBM29PL32TM/BM User Bus Operations (Word Mode : BYTE = VIH)” and “MBM29PL32TM/BM User Bus Operations (Byte Mode : BYTE = VIL)”. RA = Address of the memory location to be read. PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the write pulse. SA = Address of the sector to be programmed / erased. The combination of A20, A19, A18, A17, A16, A15, A14, A13 and A12 will uniquely select any sector. See “Sector Address Table (MBM29PL32TM)” and “Sector Address Table (MBM29PL32BM)”. SGA = Sector Group Address to be protected. See “Sector Group Address Table (MBM29PL32TM)” and “Sector Group Address Table (MBM29PL32BM)”. RD = Data read from location RA during read operation. PD = Data to be programmed at location PA. Data is latched on the rising edge of write plus. WBL = Write Buffer Location HRA = Address of the HiddenROM area ; MBM29PL32TM (Top Boot Type)Word Mode : 1FFF7Fh to 1FFFFFh Byte Mode : 3FFEFFh to 3FFFFFh MBM29PL32BM (Bottom Boot Type)Word Mode : 000000h to 00007Fh Byte Mode : 000000h to 0000FFh *1 : The command combinations not described in “MBM29PL32TM/BM Standard Command Definitions” are illegal. *2 : Both of these reset commands are equivalent except for "Write to Buffer Abort" reset. *3 : The Erase Suspend and Erase Resume command are valid only during a sector erase operation. *4 : The Set to Fast Mode command is required prior to the Fast Program command. *5 : The Reset from Fast Mode command is required to return to the read mode when the device is in fast mode. *6 : Reset to the read mode. The Write to Buffer Abort Reset command is required after the Write to Buffer operation was aborted. *7 : This command is valid while RESET = VID. *8 : Sector Group Address (SGA) with A6 = 0, A3 = 0, A2 = 0, A1 = 1, and A0 = 0 *9 : The valid address are A6 to A0. *10 : The HiddenROM Entry command is required prior to the HiddenROM programming. *11 : This command is valid during HiddenROM mode. *12 : The data “F0h” is also acceptable. *13 : Indicates read cycle. |
