Pins
| Pin | Config | Pull up | Function | Comment | |
| A0-A22 | Special Function | All these pins have their special functions. | |||
| B0 | nXDREQ0 | Disabled | DMA Request? What is this connected to? | ||
| B1 | Output | Enabled | Backlight | Non-zero to turn on the backlight | |
| B2 | Output | Disabled | IrDA enable | 0=transceiver enabled, 1=disabled | |
