 10.1.22. AFU Download Address Register (AFU_DLADDR)

 The AFU Download Address Register (AFU_DLADDR) is used to control the configuration of an AFU.

 There is only one register for the PSL. Access to this register should be privileged. This register must be accessed using a single 64-bit store operation.

 This register is optional for CAIA-compliant devices that do not support loadable AFUs. System software can detect if this feature is supported by writing x'0FFFFFFFFFFFFF80' to this register and reading back the contents. If a value of zero is returned, this feature is not supported. Any nonzero value indicates that the feature is supported.
