9 / 18 page Serial Data Transfer Examples • At the LC75834E and LC75834W when109 or more segments are used, at the LC75834JE when 97 or more segments are used,192 bits of serial data must be sent. Note: At the LC75834JE, the display data D33 to D36, D69 to D72, D105 to D108, D133 to D136 must be set to 0. • At the LC75834E and LC75834W when used with less than 109 segments, at the LC75834JE when used with less than 97 segments, transfer either 48 bits, 96 bits or 144 bits of serial data depending on the number of segments used. However, the serial data shown in the figure below (the display data D1 to D36 and the control data) must be sent. Note: At the LC75834JE, the display data D33 to D36 must be set to 0. Control Data Functions 1. P0 to P3: Segment output port/general-purpose output port switching control data. These control data bits switch the S1/P1 to S8/P8 output pins between their segment output port and general-purpose output port functions. Note: Sn (n = 1 to 8): Segment output ports Pn (n = 1 to 8): General-purpose output ports No. 5597-9/18 LC75834E, 75834W, 75834JE Control data Output pin states P0 P1 P2 P3 S1/P1 S2/P2 S3/P3 S4/P4 S5/P5 S6/P6 S7/P7 S8/P8 0 0 0 0 S1 S2 S3 S4 S5 S6 S7 S8 0 0 0 1 P1 S2 S3 S4 S5 S6 S7 S8 0 0 1 0 P1 P2 S3 S4 S5 S6 S7 S8 0 0 1 1 P1 P2 P3 S4 S5 S6 S7 S8 0 1 0 0 P1 P2 P3 P4 S5 S6 S7 S8 0 1 0 1 P1 P2 P3 P4 P5 S6 S7 S8 0 1 1 0 P1 P2 P3 P4 P5 P6 S7 S8 0 1 1 1 P1 P2 P3 P4 P5 P6 P7 S8 1 0 0 0 P1 P2 P3 P4 P5 P6 P7 P8 |
