• T0/XCK0/PCINT8, Bit 0
T0, Timer/Counter0 counter source.
XCK0, USART0 External clock. The Data Direction Register (DDB0) controls whether the clock
is output (DDD0 set “one”) or input (DDD0 cleared). The XCK0 pin is active only when the
USART0 operates in Synchronous mode.
PCINT8, Pin Change Interrupt source 8: The PB0 pin can serve as an external interrupt source.
