Normal blinking is assumed when the LCD multiplex drive modes 1:3 or 1:4 are selected.
Alternate RAM bank blinking does not apply in 1:3 and 1:4 multiplex drive modes.
7.19 Display controller
The display controller executes the commands identified by the command decoder. It
contains the status registers of the PCA8576C and coordinates their effects. The
controller is also responsible for loading display data into the display RAM as required by
the filling order.
