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 (A20 to A15)

4.RD = Data read from location RA during the 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

29PDS322TE (Top Boot Type)Word Mode:1F8000h to 1FFFFFh

29PDS322BE (Bottom Boot Type)Word Mode:000000h to 007FFFh

7.HRBA =Bank Address of the Hi-ROM area

29PDS322TE (Top Boot Type):A20 = A19 = A18 = A17 = A16 = A15 = 1

29PDS322BE (Bottom Boot Type):A20 = A19 = A18 = A17 = A16 = A15 = 0

8.The system should generate the following address patterns:

Word Mode: 555h or 2AAh to addresses A10 to A0

9.Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
