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 DDB3. When the
SPI is enabled as a Master, the data direction of this pin is controlled by DDB3. When the
pin is forced by the SPI to be an input, the pull-up can still be controlled by the PORTB3 bit.
OC2, Output Compare Match Output: The PB3 pin can serve as an external output for the
Timer/Counter2 Compare Match. The PB3 pin has to be configured as an output (DDB3 set
(one)) to serve this function. The OC2 pin is also the output pin for the PWM mode timer
function.
PCINT3: Pin Change Interrupt source 3. The PB3 pin can serve as an external interrupt
source.
SS: Slave Select input. When the SPI is enabled as a Slave, this pin is configured as an
input regardless of the setting of DDB2. 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 DDB2. When the pin is forced by the SPI to be an input, the pull-up can still be controlled
by the PORTB2 bit.
OC1B, Output Compare Match output: The PB2 pin can serve as an external output for the
Timer/Counter1 Compare Match B. The PB2 pin has to be configured as an output (DDB2
set (one)) to serve this function. The OC1B pin is also the output pin for the PWM mode
timer function.
PCINT2: Pin Change Interrupt source 2. The PB2 pin can serve as an external interrupt
source.
OC1A, Output Compare Match output: The PB1 pin can serve as an external output for the
Timer/Counter1 Compare Match A. The PB1 pin has to be configured as an output (DDB1
set (one)) to serve this function. The OC1A pin is also the output pin for the PWM mode
timer function.
PCINT1: Pin Change Interrupt source 1. The PB1 pin can serve as an external interrupt
source.
ICP1, Input Capture Pin: The PB0 pin can act as an Input Capture Pin for Timer/Counter1.
CLKO, Divided System Clock: The divided system clock can be output on the PB0 pin. The
divided system clock will be output if the CKOUT Fuse is programmed, regardless of the
PORTB0 and DDB0 settings. It will also be output during reset.
PCINT0: Pin Change Interrupt source 0. The PB0 pin can serve as an external interrupt
source.
