Active Force Control
Pins 3-6 are used to set the target force. These pins form a 4-bit word where pin 3 is the
least significant bit and pin 6 is the most significant bit. The value represented on these
pins determines the force register index to be used e.g., 0101 will select force register
index 5. Set pin 7 high to start active force control.

Initiate Calibration
Pin 8 can be used to initiate the calibration routine. See section
Load Calibration for information on the calibration procedure. To initiate the calibration
routine a pulse should be applied to the pin, but no longer than 2 seconds.
