= 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 A

uniquely select any sector.
BA = Bank address (A

HRA= Address of the Hidden-ROM area.
MB84VD2218XEC/EE (Top Boot Type) Word mode: 1F8000H to 1FFFFFH
Byte mode: 3F0000H to 3FFFFFH
MB84VD2219XEC/EE (Bottom Boot Type) Word mode: 000000H to 007FFFH
Byte mode: 000000H to 00FFFFH

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 A
