/* Set Re-map
*
* This double command has multiple configurations and each bit setting is
* described as follows:
*
* 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):
*
* Byte 1: 0xa0
* Byte 2: A[7:0]
