Why does my program run slowly from PFLASH?

Hello,

Why does my program execute much faster from RAM than from PFLASH?

Thank you.

Regards
Bernie

Hi,

The FSI2 clock is used for reading from PFLASH. Make sure that CCUCON0.FSI2DIV is set to the maximum allowed frequency (fFSI2 in the datasheet).

For best performance, also ensure that you have enabled program cache (PCON0.PCBYP=0), and that you are executing from the cached segment (0x8 instead of 0xA).

Regards
Lucas
