14.3.1 Alternate Functions of Port B
The Port B pins with alternate functions are shown in Table 14-3.
The alternate pin configuration is as follows:
XTAL2/TOSC2/PCINT7 – Port B, Bit 7
XTAL2: chip clock oscillator pin 2. Used as clock pin for crystal oscillator or low-frequency crystal oscillator. When used as a
clock pin, the pin can not be used as an I/O pin.
TOSC2: Timer oscillator pin 2. Used only if internal calibrated RC oscillator is selected as chip clock source, and the
asynchronous timer is enabled by the correct setting in ASSR. When the AS2 bit in ASSR is set (one) and the EXCLK bit is
cleared (zero) to enable asynchronous clocking of Timer/Counter2 using the crystal oscillator, pin PB7 is disconnected from
the port, and becomes the inverting output of the oscillator amplifier. In this mode, a crystal oscillator is connected to this pin,
and the pin cannot be used as an I/O pin.
PCINT7: Pin change interrupt source 7. The PB7 pin can serve as an external interrupt source.
If PB7 is used as a clock pin, DDB7, PORTB7 and PINB7 will all read 0.
XTAL1/TOSC1/PCINT6 – Port B, Bit 6
XTAL1: chip clock oscillator pin 1. Used for all chip clock sources except internal calibrated RC oscillator. When used as a
clock pin, the pin can not be used as an I/O pin.
TOSC1: Timer oscillator pin 1. Used only if internal calibrated RC oscillator is selected as chip clock source, and the
asynchronous timer is enabled by the correct setting in ASSR. When the AS2 bit in ASSR is set (one) to enable
asynchronous clocking of Timer/Counter2, pin PB6 is disconnected from the port, and becomes the input of the inverting
oscillator amplifier. In this mode, a crystal oscillator is connected to this pin, and the pin can not be used as an I/O pin.
PCINT6: Pin Change Interrupt source 6. The PB6 pin can serve as an external interrupt source.
If PB6 is used as a clock pin, DDB6, PORTB6 and PINB6 will all read 0.
