Note: This table assumes that pins S1/P1 to S12/P12 and S37/OSCI are configured for segment output.
In addition, in the case of the LC75890E(QIP44M), the display data are effective for only D1 to D44, D49 to D92,
D97 to D136, and D145 to D148, the display blinking control data are effective for only BD1 to BD11, BD13 to
BD23, BD25 to BD34, and BD37. (In the case of the LC75890E(QIP44M), the output pins are effective for only
S1/P1 to S11/P11, S13 to S23, S25 to S34, and S37/OSCI pins.)
For example, the table below lists the output states for the S21 output pin.
