Timer/Counter0 Compare Match B. The PB1 pin has to be configured as an output (DDB1
set (one)) to serve this function. The OC0B pin is also the output pin for the PWM mode timer
function.

PORTB1 still enables the pull-up, if the direction is input and PORTB1 is set (one).
as a Slave, this pin is configured as an input regardless of the setting of DDB0. When the SPI
is enabled as a Master, the data direction of this pin is controlled by DDB0. When the pin is
forced by the SPI to be an input, the pull-up can still be controlled by the PORTB0 bit.
