FAQ NO : 102749 Issue Date : Mar.25.09 Functions : LCD I'd like to know how to adjust the LCD panel's luminance in the 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.

FAQ NO : 102753 Issue Date : Mar.25.09 Functions : LCD Please explain the calculation formula for frame frequency. When using system clock, a frame frequency= clock frequency used /512. When using sub-clock, a frame frequency= clock used/256. Note that when selecting 1/3 duty, the value is multiplied by three-forths from the above formula.

FAQ NO : 102741 Issue Date : Mar.25.09 Functions : PWM Output When the PWM data register (PWDR) is rewritten during PWM output on the H8/3802, H8/38004 and H8/38024 Groups, how does an output waveform vary? When rewriting the PWDR during a high period, the waveform varies immediately after rewriting. When the duty cycle is reduced during a low period, the waveform varies immediately after rewriting, but when duty is increased during rewriting, the...

FAQ NO : 102734 Issue Date : Mar.25.09 Functions : Serial Interface When initializing the SCI, a waiting time of at least 1 bit is provided before TE bit or RE bit of Serial Control Register (SCR) is set to 1. What is the reason? The waiting period of 1 bit is the minimum time in order to initialize the internal state of SCI. If you don't wait the time before sending the data, erroneous data may be sent.

FAQ NO : 102735 Issue Date : Mar.25.09 Functions : Serial Interface What is the initial value of TxD pin, when the TE bit of serial control register (SCR) is set to 1? When TE bit is set to 1, the initial value of TxD pin becomes high level automatically in the asynchronous and clock synchronous modes. However, it is necessary to set to 1 the SPC3 bit of the serial port control register (SPCR) before TE bit is ...
