5: This command is valid while Hi-ROM mode.
6: The data “00h” is also acceptable.
Address bits A11 to A20 = X = “H” or “L” for all address commands except for Program Address (PA),
Sector Address (SA),and Bank Address (BA).
Bus operations are defined in Table 2 "User Bus Operations".
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)
SPA = Sector group address to be protected. Set sector group address (SGA) and (A6, A1, A0) = (0, 1, 0).
HRA= Address of the Hidden-ROM area.
MB84VD2228XEA/EE (Top Boot Type) Word mode: 1F8000h to 1FFFFFh
Byte mode: 3F0000h to 3FFFFFh
MB84VD2229XEA/EE (Bottom Boot Type) Word mode: 000000h to 007FFFh
Byte mode: 000000h to 00FFFFh
HRBA = Bank address of the Hidden-ROM area
MB84VD2228XEA/EE (Top Boot Type) : A15 = A16 = A17 = A18 = A19 = A20 = 1
MB84VD2229XEA/EE (Bottom Boot Type) : A15 = A16 = A17 = A18 = A19 = A20 = 0
RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA.
SD = Sector protection verify data. Output 01h at protected sector addresses and output 00h
at unprotectedsector addresses.
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
