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 “MBM29DL16XTE/BE 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 (A19 to A15)

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

29DL16XTE (Top Boot Type) Word Mode: 0F8000h to 0FFFFFh

Byte Mode: 1F0000h to 1FFFFFh

29DL16XBE (Bottom Boot Type) Word Mode: 000000h to 007FFFh

Byte Mode: 000000h to 00FFFFh

HRBA: Bank Address of the HiddenROM area

29DL16XTE (Top Boot Type) :A19 = A18= A17 = A16 = A15 = VIH

29DL16XBE (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 Command Definitions table are illegal.

*1: Both of these reset commands are equivalent.

*2: This command is valid during Fast Mode.

*3: This command is valid while RESET = VID (except during HiddenROM MODE).

*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.
