ATmega164A/PA/324A/PA/644A/PA/1284/P
OC3A, Output Compare Match A output: The PB6 pin can serve as an external output for the
Timer/Counter0 Output Compare. The pin has to be configured as an output (DDB6 set “one”) to
serve this function. The OC3A pin is also the output pin for the PWM mode timer function.
PCINT14, Pin Change Interrupt source 14: The PB6 pin can serve as an external interrupt
source.
• MOSI/ICP3/PCINT13 – Port B, Bit 5
MOSI: SPI Master Data output, Slave Data input for SPI channel. When the SPI is enabled as a
slave, this pin is configured as an input regardless of the setting of DDB5. When the SPI is
enabled as a master, the data direction of this pin is controlled by DDB5. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB5 bit.
ICP3, Input Capture Pin 3: The PB5 pin can act as an input capture pin for Timer/Counter3.
PCINT13, Pin Change Interrupt source 13: The PB5 pin can serve as an external interrupt
source.
• SS/OC0B/PCINT12 – Port B, Bit 4
SS: Slave Port Select input. When the SPI is enabled as a slave, this pin is configured as an
input regardless of the setting of DDB4. As a slave, the SPI is activated when this pin is driven
low. When the SPI is enabled as a master, the data direction of this pin is controlled by DDB4.
When the pin is forced to be an input, the pull-up can still be controlled by the PORTB4 bit.
OC0B, Output Compare Match B output: The PB4 pin can serve as an external output for the
Timer/Counter0 Output Compare. The pin has to be configured as an output (DDB4 set “one”) to
serve this function. The OC0B pin is also the output pin for the PWM mode timer function.
PCINT12, Pin Change Interrupt source 12: The PB4 pin can serve as an external interrupt
source.
• AIN1/OC0A/PCINT11, Bit 3
AIN1, Analog Comparator Negative input. This pin is directly connected to the negative input of
the Analog Comparator.
OC0A, Output Compare Match A output: The PB3 pin can serve as an external output for the
Timer/Counter0 Output Compare. The pin has to be configured as an output (DDB3 set “one”) to
serve this function. The OC0A pin is also the output pin for the PWM mode timer function.
PCINT11, Pin Change Interrupt source 11: The PB3 pin can serve as an external interrupt
source.
• AIN0/INT2/PCINT10, Bit 2
AIN0, Analog Comparator Positive input. This pin is directly connected to the positive input of
the Analog Comparator.
INT2, External Interrupt source 2. The PB2 pin can serve as an External Interrupt source to the
MCU.
PCINT10, Pin Change Interrupt source 10: The PB2 pin can serve as an external interrupt
source.
• T1/CLKO/PCINT9, Bit 1
T1, Timer/Counter1 counter source.
