Alternate Functions of Port D
Table 13-11. Overriding Signals for Alternate Functions in PC3:PC0
Note:
The Port D pins with alternate functions are shown in
Table 13-12. Port D Pins Alternate Functions
Note:
The alternate pin configuration is as follows:
• T2 – Port D, Bit 7
T2, Timer/Counter2 Counter Source.
• T1 – Port D, Bit 6
T1, Timer/Counter1 Counter Source.
• XCK1 – Port D, Bit 5
XCK1, USART1 External Clock. The Data Direction Register (DDD5) controls whether the clock
is output (DDD5 set) or input (DDD5 cleared). The XCK1 pin is active only when the USART1
operates in synchronous mode.
• ICP1 – Port D, Bit 4
ICP1 – Input Capture Pin1: The PD4 pin can act as an Input Capture pin for Timer/Counter1.
