Hello invisigothux,

This is by setting XPEN bit in SYSCON register and XFLASHEN bit in XPERCON register.

Note: The XPERCON register MUST be written BEFORE the XPEN bit in SYSCON is SET because Register XPERCON cannot be changed after the global enabling of X-Peripherals, i.e. after setting of bit XPEN in

SYSCON register.

Regards,

Najoua.
