Port a alternate functions
WebMar 26, 2012 · Instead, each peripheral connects or disconnects itself to the corresponding port pin. Take PWM as an example. To set PWM 1 in fast mode, you need to connect it to port pins using the four high bits of TCCR1A. TCCR1A is a dedicated register to timer 1 and not a general pin selection register. Hope it is more clear for you now. WebJul 19, 2024 · Alternate function Mode. GPIO pins have the capability of providing an alternate function apart from the regular three modes. The pins are multiplexed to provide functionalities like USART Tx pin, I2C data pin, etc. There will be a separate register to set the alternate functions.

Port-1 does not have any alternate function i.e. it is dedicated solely for I/O interfacing. When used as output port, the pin is pulled up or down through internal pull-up. To use port-1 as input port, '1' has to be written to the latch.
