| 15 | +- QIO (Quad I/O): Uses 4 data lines for input/output, allowing faster data transfer between the microcontroller and flash memory. |

| 16 | +- DIO (Dual I/O): Uses 2 data lines for input/output, offering a balance between speed and compatibility. |
|
| 17 | +- DOUT (Dual Output): Uses 2 data lines but only for output (reading from flash), typically slower than DIO and QIO. |
