7 List MSB first and LSB last.
8 The status register or data is read out at least once and is continuously read out until the nCS pin is driven high.
9 This operation is not applicable for EPCQ4A.
10 A write bytes operation requires at least one data byte. If more than 256 bytes are sent to the device, only the last 256 bytes are written to the memory.
