Alternate Functions of Port D
The Port D pins with alternate functions are shown in Table 11-12.
The alternate pin configuration is as follows:
T0 – Port D, bit 7
T0, Timer/Counter0 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.
