Bus operations are defined in “MBM29LV400TC/400BC User Bus Operations Tables (BYTE = V
RA = Address of the memory location to be read
PA = Address of the memory location to be programmed
SA = Address of the sector to be erased. The combination of A
RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
The system should generate the following address patterns:
Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
