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
