8059D–AVR–11/09
CLKO, Divided System Clock: The divided system clock can be output on the PB1 pin. The
divided system clock will be output if the CKOUT Fuse is programmed, regardless of the
PORTB1 and DDB1 settings. It will also be output during reset.
PCINT9, Pin Change Interrupt source 9: The PB1 pin can serve as an external interrupt source.
• 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.
