Hello,

The frequency of input CLK (crystal oscillator) can be selected from 19.2 MHz, 26 MHz, 38.4 MHz and 52 MHz.

Are there any recommended for use with DMA and SPI 33 MHz?

Best Regards,

Naoaki Morimoto

Hello Morimoto-san,

There are no any recommendation.

We can declare any (up to 33MHz and at least 10kHz) frequency by using CyU3PSpiSetConfig() API irrespective of the crystal oscillator if it is selected from 19.2 MHz, 26 MHz, 38.4 MHz or 52 MHz.

Best regards,

Hirotaka Takayama
