+ Sharp Memory LCDs are a series of monochrome displays that operate over
+ a SPI bus. The displays require a signal (VCOM) to be generated to prevent
+ DC bias build up resulting in pixels being unable to change. Three modes
+ can be used to provide the VCOM signal ("software", "external", "pwm").

+ software - This mode relies on a software operation to send a

+ bit on and off with each message
+
+ external - This mode relies on an external clock to generate
+ the signal on the EXTCOMM pin
+
+ pwm - This mode relies on a pwm device to generate the signal
+ on the EXTCOMM pin
