4.3. Energy Harvest Launch Mode
This mode is used when the EHC is used for operation. See section "3.5EH (Energy
Harvesting) Power Supply Mode" for jumper pin and switch settings for EH power supply
mode.
After charging the VCC_SU capacitor from the generator connected to VSC_VCC, the
EHC will start to supply power to VCC. When the reset is released by a power-on reset,
the back bias voltage control (VBBC) circuit is initialized, and the user program written in
the code flash memory is executed.
