5.2.5 Remote Switcher Connector (J5)
The remote switcher connector inputs and outputs various signals that make it possible for the user to develop a
separate switching block, while still using the digital logic of the DK card to power the motor control IC.
Signal
AmpliferEnable
Pin # Description
1
This signal is connected to the AmplifierDisable signal from MC73110. It can be
programmed to go inactive under certain erroneous MCP conditions
PWMOutputDisable 2
This signal provides a digital input connected to the MC73110 pin of the same name.
A high level on this signal indicates that PWMOutputDisable is not active, a low
indicates it is active.
