8127F–AVR–02/2013
PCINT1: Pin Change Interrupt source 1. The PB1 pin can serve as an external interrupt source for pin change
interrupt 0.
TPICLK: Serial Programming Clock.
Port B, Bit 2 – ADC2/CLKO/INT0/PCINT2/T0
ADC2: Analog to Digital Converter, Channel 2 (ATtiny5/10, only)
CLKO: System Clock Output. The system clock can be output on pin PB2. The system clock will be output if
CKOUT bit is programmed, regardless of the PORTB2 and DDB2 settings.
INT0: External Interrupt Request 0
PCINT2: Pin Change Interrupt source 2. The PB2 pin can serve as an external interrupt source for pin change
interrupt 0.
T0: Timer/Counter0 counter source.
Port B, Bit 3 – ADC3/PCINT3/RESET
ADC3: Analog to Digital Converter, Channel 3 (ATtiny5/10, only)
PCINT3: Pin Change Interrupt source 3. The PB3 pin can serve as an external interrupt source for pin change
interrupt 0.
RESET:
Table 10-4 and Table 10-5 on page 50 relate the alternate functions of Port B to the overriding signals shown in
Table 10-4.
Overriding Signals for Alternate Functions in PB3..PB2
Notes:
1. RSTDISBL is 1 when the configuration bit is “0” (Programmed).
2. CKOUT is 1 when the configuration bit is “0” (Programmed).
