Connector P4

The index mask masks the index input of the encoder so that the encoder
 index can be combined with a mechanical switch or opto detector to clear
 or latch the encoder counter only when the mask input bit is in proper
 state (selected by mask polarity bit) and encoder index occurs.
 This is useful for homing.
 The behaviour of these pins is controlled by the Counter Control Register
 (CCR), however there is currently no function in the driver to change the
 CCR.
