10 / 74 page  MBM29DL16XTD/BD-70/90 10 *4 : The valid addresses are A6 to A0. *5 : This command is valid during HiddenROM mode. *6 : The data “00h” is also acceptable. *7 : The fourth bus cycle is only for read. Notes: • Address bits A19 to A11 = X = “H” or “L” for all address commands except or Program Address (PA), Sector Address (SA), and Bank Address (BA). • Bus operations are defined in “MBM29DL16XTD/BD User Bus Operations Tables (BYTE = VIH and BYTE = VIL)”. • RA = Address of the memory location to be read IA = Autoselect read address that sets both the bank address specified at (A19, A18, A17, A16, A15) and all the other A6, A1, A0, (A-1) . 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 A19, A18, A17, A16, A15, A14, A13, and A12 will uniquely select any sector. BA = Bank Address (A15 to A19) • RD = Data read from location RA during read operation. ID = Device code/manufacture code for the address located by IA. PD = Data to be programmed at location PA. Data is latched on the rising edge of write pulse. • SPA = Sector group address to be protected. Set sector group address (SGA) and (A6, A1, A0) = (0, 1, 0). SD = Sector group protection verify data. Output 01h at protected sector group addresses and output 00h at unprotected sector group addresses. • HRA = Address of the HiddenROM area 29DL16XTD (Top Boot Type) Word Mode: 0F8000h to 0FFFFFh Byte Mode: 1F0000h to 1FFFFFh 29DL16XBD (Bottom Boot Type) Word Mode: 000000h to 007FFFh Byte Mode: 000000h to 00FFFFh • HRBA =Bank Address of the HiddenROM area 29DL16XTD (Top Boot Type) :A19 = A18 = A17 = A16 = A15 = VIH 29DL16XBD (Bottom Boot Type) :A19 = A18 = A17 = A16 = A15 = VIL • The system should generate the following address patterns: Word Mode: 555h or 2AAh to addresses A10 to A0 Byte Mode: AAAh or 555h to addresses A10 to A0 and A–1 • Both Read/Reset commands are functionally equivalent, resetting the device to the read mode. • Command combinations not described in “MBM29DL16XTD/BD Command Definitions Table” are illegal. |
