is driven to the port when the data direction bit DDA5 is set (one). However the PORTA5 bit
still controls the pullup, enabling pullup if direction is input and PORTA5 is set(one).
a Master, this pin is configured as an input regardless of the setting of DDA5. When the SPI is
enabled as a Slave, the data direction of this pin is controlled by DDA5. When the pin is
forced by the SPI to be an input, the pull-up can still be controlled by the PORTA5 bit.
Timer/Counter1 Compare Match B. The PA5 pin has to be configured as an output (DDA5 set
(one)) to serve this function. The OC1B pin is also the output pin for the PWM mode timer
function.
