FAQs

  1. How to adjust the luminance in H8/3802, H8/38004 and H8/38024 Groups?

    Please adjust the luminance by inserting a variable resistor between Vcc and V1. Since driving power is supplied externally, please set PSW bit to 0.

  2. How are I/O ports when move with no sub oscillator on H8/3802, H8/38024?

    The port maintains the status it had immediately before the transfer for both input and output port. It is not recommended to transfer to the sub-clock type mode without connecting a sub-oscillator. If not connecting to any sub-oscillator be sure to fix X1 pin to GND.
