max freq for SPCK for sam3A4C as slave SPI?

Sun Oct 26, 2014 2:42 am

For SAM3A4C, the device is configured as SPI slave, it reads data from a master SPI device and DMA the data to SRAM, what is the max supported incoming SPCk frequency?

The datasheet says it is up to the SPCK pad, but the I/O has max freq on the output freq, not input. 

I want to run it at 64MHZ if possible.

See discussions/viewtopic.php/f,24/t,22116.html

I suspect these are the kind of clock speeds to expect.
