3.4.2 External HW Control
Also Low Speed Signals are controllable using an external source, this could be done
through J6 (H_LPWN pin) and J7 (H_RSTN Pin) pin headers. In this case a jumper should be
placed on pin header J1 (HW_CTRL) shown in the image below.
When the jumper is inserted on J1, the output signals are tri-stated from the
microcontroller, and hence could be controlled from the external source.

The low speed signals circuit shown below shows the connection of these signals to the
microcontroller and DSFP connector.

ML4019-MCB Software
The ML4019-MCB is accessible and controlled through application software. This software is
MSA compliant and provides a user-friendly interface to operate the board and access all
features. The communication between the ML4019-MCB board and the software is established
through USB connection.
