DEMOJM User Manual
Mini-USB Port
J7 – CAN Transmit Enable CTE
J8 – CAN Port Enable CAN_EN
J10 – USB Host FAULT signal.
J11- USB Host Voltage Enable VHOST_EN
By default, this jumper is installed to enable CAN transmission.
Enables CAN port. By default, the jumpers are installed.
The DEMOJM board integrates a Mini-AB USB port. It can operate in both
device mode and host mode using jumper settings.
If the jumper is installed, the FAULT signal is connected to the
microcontroller’s IRQ pin. By default, this jumper is not installed.
This jumper enables or disables USB host mode power generation.
A jumper across 1 & 2 disables USB host power generation. This selection
also pulls up PTB3 and allows the microcontroller to use PTB3 to control the
USB host power generation. Pay extra attention to this signal as it is shared
