• RD = Data read from location RA during read operation.
ID = Device code/manufacture code for the address located by IA.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
• SPA = Sector address to be protected. Set sector address (SA) and (A6, A1, A0) = (0, 1, 0) .
SD = Sector protection verify data. Output 01h at protected sector addressed and output 00h at
unprotected sector addresses.
• The system should generate the following address patterns :
Word Mode : 555h or 2AAh to addresses A10 to A0
Byte Mode : AAAh or 555h to addresses A10 to A-1
• Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
• The command combinations not described in Command Definitions are illegal.
