INTERNAL BUS CLOCK: This pin controls the speed of the controller
DMA function. When CLKSEL of configuration C is set low, this pin
should be tied to ground.

TEST: This pin is only used for industry test. It should be left
unconnected in normal operation (because it has internal pulldown
resistor).
