Alternate Functions of Port C The Port C has an alternate function as SEG for the LCD Controller.
The alternate pin configuration is as follows:
• SEG – Port D, Bit 7:0
SEG, LCD front plane 5/5, 6/6, 11/7-16/12.
Table 34 and Table 35 relate the alternate functions of Port C to the overriding signals
shown in Figure 27 on page 65.
