8 / 16 page Serial Data Transfer Example 1. When 201 or more segments are used All 320 bits of serial data must be sent. 2. When fewer than 201 segments are used Either 80, 160 or 240 bits of serial data may be sent, depending on the number of segments used. However, the serial data shown below (the D1 to D68 display data and the control data) must be sent. Control Data Functions 1. P0 to P3: Segment output port/general-purpose output port switching control data These control data bits switch the segment output port/general-purpose output port functions of the S1/P1 to S8/P8 output pins. Note: Sn (n = 1 to 8): Segment output port function Pn (n = 1 to 8): General-purpose output port function Note that when the general-purpose output port function is selected, the correspondence between the output pins and the display data will be that shown in the table. For example, if the general-purpose output port function is selected for the S4/P4 output pin, that output pin will output a high level (VLCD) when the display data D13 is 1, and a low level (VSS) when the D13 is 0.
