I just tried to use PIO0_10 and 11 as digital output pins and found out the hard way that they have open drain output drivers. Am I correct to assume that all other periphericals that can be connected to those pins via the switch matrix would also use the same output drivers? In that case most of the other output functions (e.g. SPI, UART) would not work correctly either?
