Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 13-12. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• SEG15 - SEG20 – Port D, Bit 7:2
SEG15-SEG20, LCD front plane 15-20.
• INT0/SEG21 – Port D, Bit 1
INT0, External Interrupt Source 0. The PD1 pin can serve as an external interrupt source to the
MCU.
