*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.

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.
