RD = Data read from location RA during read operation. PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE# or CE# pulse, whichever happens later. PD = Data to be programmed at location PA. Data latches on the rising edge of WE# or CE# pulse, whichever happens first. SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits A19–A12 uniquely select any sector. |
