Table 11. Port power supply groups
In the RH850/F1H, F1KM-S4 and F1KH-D8 versions of the board a 3.3V regulator is supplied to
provide the required voltage for the Ethernet transceiver. This voltage is supplied to the BVCC
Pin Group Power Supply and will affect the ports P10, P11, P12 and P18 (blue area in Figure 8).
All other port pins operate at 5 V (red area in Figure 8). For RH850/F1L and RH850/F1K all port
pins operate at 5 V.

4.2.3.1 RGB LED
A RGB LED is provided to allow visual observation of microcontroller output port state and to
show the functionality of the PWM Diagnostic Macro. The RGB LED, which is part of the Rotary
Encoder, is driven by three N-channel transistor. A feedback for each RGB LED channel is
