Alternate Functions of Port D
The Port D pins with alternate functions are shown in Table 13-12.
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.
SEG21, LCD front plane 21.
ICP1/SEG22 – Port D, Bit 0
ICP1 – Input Capture pin1: The PD0 pin can act as an Input Capture pin for Timer/Counter1.
SEG22, LCD front plane 22.
