11 / 80 page MBM29DL32XTE/BE-80/90/12 11 (Continued) *1: This command is valid while Fast Mode. *2: This command is valid while RESET = VID. *3: The valid addresses are A6 to A0. *4: This command is valid while Hi-ROM mode. Notes: 1. Address bits A11 to A20 = X = “H” or “L” for all address commands except or Program Address (PA), Sector Address (SA), and Bank Address (BA). 2. Bus operations are defined in Tables 3 and 4. 3. 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 A20, A19, A18, A17, A16, A15, A14, A13, and A12 will uniquely select any sector. BA = Bank Address (A15 to A20) 4. RD = Data read from location RA during read operation. PD = Data to be programmed at location PA. Data is latched on the falling edge of write pulse. 5. 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. 6. HRA = Address of the Hi-ROM area 29DL32XTE (Top Boot Type) Word Mode: 1F8000h to 1FFFFFh Byte Mode: 3F0000h to 3FFFFFh 29DL32XBE (Bottom Boot Type) Word Mode: 000000h to 007FFFh Byte Mode: 000000h to 00FFFFh 7. HRBA = Bank Address of the Hi-ROM area 29DL32XTE (Top Boot Type) :A15 = A16= A17 = A18 = A19 = A20 = 1 29DL32XBE (Bottom Boot Type) :A15 = A16= A17 = A18 = A19 = A20 = 0 8. The system should generate the following address patterns: Word Mode: 555h or 2AAh to addresses A0 to A10 Byte Mode: AAAh or 555h to addresses A–1 and A0 to A10 9. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode. |
