2. Bus operations are defined in Tables 2 and 3.
3. RA = Address of the memory location to be read
4. RD = Data read from location RA during read operation.
5. The system should generate the following address patterns:
6. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
Sector Address (SA)
PA = Address of the memory location to be programmed
SA = Address of the sector to be erased. The combination of A
PD = Data to be programmed at location PA. Data is latched on the falling edge of WE.
