• CCB address ......................... “50H”
• D1 to D37 ............................. Display data
Note : In the case of the LC75890E(QIP44M), the display data are effective for only D1 to D11, D13 to D23,
D25 to D34, and D37.
• BD1 to BD37 ........................ Display blinking control data of each segment output pin
Note : In the case of the LC75890E(QIP44M), the control data are effective for only BD1 to BD11, BD13 to BD23,
BD25 to BD34, and BD37.
• BF0 to BF2 ........................... Segment blinking frequency setting control data
• FC0 to FC2 ........................... Common/segment output waveform frame frequency setting control data
• DT ........................................ 1/4-duty 1/3-bias drive or static drive switching control data
• EXF ...................................... External clock operating frequency setting control data
• OC ........................................ Internal oscillator operating mode/external clock operating mode switching control data
• SC ......................................... Segment on/off control data
• BU ........................................ Normal mode/power-saving mode control data
• W10 to W15, W20 to W25,... PWM data of the PWM output
W30 to W35
• PF0 to PF3 ............................ PWM output waveform frame frequency setting control data
• P1A, P1B to P12A, P12B ..... General-purpose output function/PWM output function switiching control data of the
general-purpose output port
Note : In the case of the LC75890E(QIP44M), the control data are effective for only P1A, P1B to P11A, P11B.
• P0 to P3 ................................ Segment output port/general-purpose output port switching control data
