8.2. HTS Demo Kit Status LED
The green Status LED (D2) indicates operating status of the HTS Demo Kit board. The board’s
HD64F2215RUBRHP MCU that controls the In-Circuit Debugging and Programming functionality of the
board also controls the LED. The LED is on when the board is connected to a USB port and receives
power.
8.3. Power Supply Requirements
The HTS Demo Kit Board is powered by the USB bus. It will draw about 50mA with no LEDs on.
8.4. Power-Up Behavior
The audio example tutorial code is pre-programmed into the Renesas M16C/26A microcontroller. If
connected to a computer’s USB port, without having installed the required Renesas software tools and
drivers, the board’s RED and AMB user LED’s will flash in an alternating pattern. The green Status LED
and the GRN and ORG user LEDs will be on.
The RED and AMB LED’s blinking frequency will vary with the light intensity measured by the board’s
photo sensor.
