| /* Set Re-map |
| * |
| * This double command has multiple configurations and each bit setting is |

| * Column Address Remapping (A[0]) |
| * This bit is made for increase the flexibility layout of segment signals in |
| * OLED module with segment arranged from left to right (when A[0] is set to 0) |
| * or from right to left (when A[0] is set to 1). |
| * |
| * Nibble Remapping (A[1]) |
| * When A[1] is set to 1, the two nibbles of the data bus for RAM access are |
| * re-mapped, such that (D7, D6, D5, D4, D3, D2, D1, D0) acts like (D3, D2, D1, |
| * D0, D7, D6, D5, D4) If this feature works together with Column Address |
| * Re-map, it would produce an effect of flipping the outputs from SEG0-127 to |
| * SEG127-SEG0. |
| * |
| * Address increment mode (A[2]) |
| * When A[2] is set to 0, the driver is set as horizontal address incremen |
| * mode. After the display RAM is read/written, the column address pointer is |
| * increased automatically by 1. If the column address pointer reaches column |
| * end address, the column address pointer is reset to column start address and |
| * row address pointer is increased by 1. |
| * |
| * When A[2] is set to 1, the driver is set to vertical address increment mode. |
| * After the display RAM is read/written, the row address pointer is increased |
| * automatically by 1. If the row address pointer reaches the row end address, |
| * the row address pointer is reset to row start address and column address |
| * pointer is increased by 1. |
| * |
| * COM Remapping (A[4]) |
| * This bit defines the scanning direction of the common for flexible layout |
| * of common signals in OLED module either from up to down (when A[4] is set to |
| * 0) or from bottom to up (when A[4] is set to 1). |
| * |
| * Splitting of Odd / Even COM Signals (A[6]) |
| * This bit is made to match the COM layout connection on the panel. When A[6] |
| * is set to 0, no splitting odd / even of the COM signal is performed. When |
| * A[6] is set to 1, splitting odd / even of the COM signal is performed, |
| * output pin assignment sequence is shown as below (for 128MUX ratio): |
