To perform a Buffer Read using the standard DataFlash buffer size (528 bytes), the opcode must be clocked into

the device followed by three address bytes comprised of 14 dummy bits and 10 buffer address bits (BFA9 - BFA0).

To perform a Buffer Read using the binary buffer size (512 bytes), the opcode must be clocked into the device

followed by three address bytes comprised of 15 dummy bits and nine buffer address bits (BFA8 - BFA0).

Following the address bytes, one dummy byte must be clocked into the device to initialize the read operation if

using opcodes D4h or D6h. The CS pin must remain low during the loading of the opcode, the address bytes, the

dummy byte (if using opcodes D4h or D6h), and the reading of data. When the end of a buffer is reached, the

device continues reading back at the beginning of the buffer. A low-to-high transition on the CS pin terminates the

read operation and tri-state the output pin (SO).
