Scratch Pad Bits [15:0]
This register contains general purpose read/write bits. These bits have no effect on
hardware configuration.
Command Initialization Bits [7:0]
This is a startup register to initial the SSD1906 which should be programmed with 0x00
before register initialization.
GPIO6 I/O Configuration
When this bit = 0, GPIO6 is configured as an input pin.
When this bit = 1, GPIO6 is configured as an output pin.
GPIO5 I/O Configuration
When this bit = 0, GPIO5 is configured as an input pin.
When this bit = 1, GPIO5 is configured as an output pin.
GPIO4 I/O Configuration
When this bit = 0, GPIO4 is configured as an input pin.
When this bit = 1, GPIO4 is configured as an output pin.
GPIO3 I/O Configuration
When this bit = 0, GPIO3 is configured as an input pin.
When this bit = 1, GPIO3 is configured as an output pin.
GPIO2 I/O Configuration
When this bit = 0, GPIO2 is configured as an input pin.
When this bit = 1, GPIO2 is configured as an output pin.
GPIO1 I/O Configuration
When this bit = 0, GPIO1 is configured as an input pin.
When this bit = 1, GPIO1 is configured as an output pin.
GPIO0 I/O Configuration
