This is a question about AC Characteristics of I/O pads (SAM4S and other products). In the I/O characteristics states "Pin Group x Maximum Output Frequency": is this limitation also applied when the I/O is configured as an input ?
It doesn't make much sense for me, but for example in 22.214.171.124 Maximum SPI frequency of SAM4S datasheet the SPCK max freq in Slave Read Mode (input) is related with the SPCK pad limit.
Thank you in advance.
