Hi,

What happens if you have MD[14] = 0 and MD[40] = 1 on an Atlas? The datasheet indicates that this is a reserved setting. Any idea of what this reserved setting does and what speed the system will run at? Can it be used with HCLK = 66 MHz?

Hello,

The settings that you describe is for x3 mode but it cannot be used with HCLK=66MHz.

Please be advized that the STPC Atlas does not support these multiplication factors and if they are selected will not be work reliably.
