6 / 56 page  MBM29PL65LM-90/10 6 MBM29PL65LM Standard Command Definitions Table*1 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 erased. The combination of A21, A20, A19, A18, A17, A16 and A15 will uniquely select any sector. See “Sector Address Table” SGA = Sector Group Address to be protected. See “Sector Group Address Table”. Specify SGA which constitutes from A21 to A17 and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0). 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 pulse. WBL = Write Buffer Location HRA = Address of the HiddenROM area ; 000000h to 00007Fh *1 : The command combinations not described in “MBM29PL65LM 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.
