Alternate Functions of Port J
Table 12-26. Overriding Signals for Alternate Functions in PH3:PH0
The Port J alternate pin configuration is as follows:
Table 12-27. Port J Pins Alternate Functions
• PCINT15:12 - Port J, Bit 6:3
PCINT15:12, Pin Change Interrupt Source 15:12. The PJ6:3 pins can serve as External Interrupt
Sources.
• XCK2/PCINT11 - Port J, Bit 2
XCK2, USART 2 External Clock. The Data Direction Register (DDJ2) controls whether the clock
is output (DDJ2 set) or input (DDJ2 cleared). The XCK2 pin is active only when the USART2
operates in synchronous mode.
PCINT11, Pin Change Interrupt Source 11. The PJ2 pin can serve as External Interrupt
Sources.
