We would like to have the Tx pin(P1.1/SOUT) open collector, so several device Tx pin can be connected in parallel.
But I can't find the register related to open collector.
Can this pin to be open collector?
There is no register to configure any of the GPIO open collector.
To configure the GPIO in pseudo open-drain mode, the weak pull-up should be disabled in the GPxPAR and an external pull up resistor should be used.
You mean treat the UART pin like a GPIO pin, I need write a software UART, toggling the pins to Tx data out?
