Override parts of BOOT_CFG1 by fuse?

Hi,

 

is it possible to override only some parts of BOOT_CFG1 by fuse?

My problem:

BOOT_CFG1 is defined by external resistors.

BOOT_MODE is set to 10 (Internal boot)

Now I need to changed SD card speed to SDR50 or SDR104 for some tests. Is it possible to override just these 2 bits? BOOT_CFG1[2,3]?

If yes, how?

Do I have to change BOOT_MODE to 00?

 

Thx,

Alexander
