bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Depending on the clock selection fuse settings, PB6 can be used as input to the…

access to a peripheral. You can not even read or write the registers! GPIO pins should be set up first the before enabling the UART. The UART core is build to emulate 16550 behaviour. So when it is enabled any data at the inputs will immediately be received . If the UART1_RX line is low (because the GPIO pins have not been set-up yet) that will be seen as a start bit and the UART will start receiving 0x00-characters. Valid stops bits are not required for the UART. (See also…
