I have a question regarding User Manual Rev. 1 - 12 Nov 2012:
On page 8 there is footnote 3: "Do not use this pads for high-speed application such as SPI or USART".

Are the pads PIO0_10 and PIO0_11 not useable at all for SPI or USART?
Or are they useable, but due to electrical characteristic (e.g. filters, ...), but only for low speed of SPI or USART?
If yes, what is the speed limit?

Is RS232 e.g. with 115200 or SPI with 400 kHz possible, because it is in the same range as I2C?
