• Bus operations are defined in “MBM29DL32XTE/BE User Bus Operations (BYTE = V
• RA = Address of the memory location to be read
• RD = Data read from location RA during read operation.
• SPA = Sector group address to be protected. Set sector group address and (A
• HRA = Address of the HiddenROM area
• HRBA = Bank Address of the HiddenROM area
• The system should generate the following address patterns :
