Bus operations are defined in Table 2.
IA = Identifier Address: 00H for manufacturer code, 01H for device code.
BA = Address within the block being erased.
WA = Address of memory location to be written.
SRD = Data read from status register. See Table 4 for a description of the status register bits.
WD = Data to be written at location WA. Data is latched on the rising edge of WE#.
IID = Data read from Intelligent Identifiers.
Following the Intelligent Identifier command, two read operations access manufacture and device codes.
Either 40H or 10H are recognized by the WSM as the Byte Write Setup command.
Commands other than those shown above are reserved by Intel for future device implementations and should not be used.
