Flash Accelerator Turn On or Off

himanshudoshi — Fri, 28 Jul 2017 14:53:39 GMT

Hello to all,

While going through an architecture of the LPCXpresso 54114, I have read about a memory unit present just before the flash memory, namely Flash accelerator. So, is there any piece of code to make it turn on or off??

Kindly, look into the attached file.

Thanks a lot in advance,

Regards,

Himanshu

Hi HIMANSHU DOSHI,

The acceleration can be enabled in register FLASHCFG[ACCEL], you can find the according information from the user manual UM10914:

More details, please refer to chapter 6.6.4 Flash accelerator functional description.

Have a great day,
Kerry

Hello Hlmanshu,

Please try this:

SYSCON->FLASHCFG &= ~(1<<4);

Wish it helps you!

Have a great day,
Kerry

Hello Kerry,

Thank you very much for your reply. I have tried as per your suggestion. But, now there is a small issue occurring.

The issue is even when I have replaced 1 with any other number for example 0 or 100 or 700. There is no change observed in the power consumption. Also, when I have removed ~ sign, no changes observed.

Why is it so? Can you clarify me a bit?

Sorry, for the trouble.

Thanking you once again,

Regards,

Himanshu
