Alternate Functions of Port D
Table 9-11.
The Port D pins with alternate functions are shown in
Table 9-12.
The alternate pin configuration is as follows:
• T0 – Port D, Bit 7
T0, Timer/Counter0 counter source.
• RXCAN/T1 – Port D, Bit 6
RXCAN, CAN Receive Data (Data input pin for the CAN). When the CAN controller is enabled
this pin is configured as an input regardless of the value of DDD6. When the CAN forces this pin
to be an input, the pull-up can still be controlled by the PORTD6 bit.
T1, Timer/Counter1 counter source.
• TXCAN/XCK1 – Port D, Bit 5
