2. Bus operations are defined in Table 2.
3. RA = Address of the memory location to be read
4. RD = Data read from location RA during read operation.
5. 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 write pulse.
Addresses are latched on the falling edge of the write pulse.
