USB suspend
The evaluation board enters the standby state when the PC is put in standby mode with the
board connected to the PC. In this mode, the microcontroller enters the USB suspend mode.
Power status LED D2 turns off indicating the standby state of the board. The board resumes
its run state when the PC exits standby mode.
Current consumption of the evaluation board in the suspend state is according to USB
specifications for low-power devices.
During suspend mode, the MCU is put in HALT mode to consume the minimum current. All
I/Os of the microcontroller shall be configured for minimum current consumption. See
Appendix A: Port configuration
mode.
The transceiver is put in suspend mode by making the SUS pin high. Also the current
flowing from the potentiometer is reduced by switching the transistor OFF.
