Note:

1. Spread must be selected OFF or ON with the hardware latch pin. These bits should not be used to turn spread ON or OFF after power up. These bits can be used to

change the spread amount, and B1[5] must be set to a 1 for these bits to have any effect on the part. If these bits are used to turn spread OFF or ON, the system must reset.
