Define the XSK_EFUSEPL_DRIVER macro to use the PL eFUSE. After defining the macro, provide the inputs defined with XSK_EFUSEPL_DRIVER to burn the bits in PL eFUSE bits. If the bit is to be burned, define the macro as TRUE; otherwise define the macro as FALSE. The table below lists the user-configurable PL eFUSE parameters for Zynq devices.

Macro Name Description
XSK_EFUSEPL_FORCE_PCYCLE_RECONFIG Default = FALSE.

TRUE disables the eFUSE write to FUSE_AES and FUSE_USER blocks. FALSE does not affect the EFUSE bit.

XSK_EFUSEPL_DISABLE_AES_KEY_READ Default = FALSE.

TRUE disables the write to FUSE_AES and FUSE_USER key and disables the read of FUSE_AES. FALSE does not affect the eFUSE bit.

XSK_EFUSEPL_DISABLE_USER_KEY_READ Default = FALSE.
