To configure the DECAY select jumper:
(a) Use position JP3-1:2 to select the MSP430 GPIO functionality (default).
(b) Use position JP3-2:3 to select the respective variable resistance
potentiometer. Allowing the jumper to not be placed, will result in the
device operating under mixed decay mode.

1.4 Motor Outputs
There are two ways of connecting the different motor styles (single bipolar stepper motor or two DC
motors) into the CPG004_DRV88xx Evaluation Module: four pin header (J4) and four position terminal
block (J3). Although feasible, we do not recommend the connection of any motor into the test clips as
these are Kelvin connections and not rated for high current output.
