Provides the syndrome value reported to software when the Effective value of SCR_EL3.DSE is 1 on taking a delegated SError exception to EL2 or EL1, or on executing an ESB instruction at EL2 or EL1.
When the delegated SError exception injected using SCR_EL3.DSE is taken to EL2 using AArch64, then the syndrome value is reported in ESR_EL2.
When the delegated SError exception injected using SCR_EL3.DSE is taken to EL1 using AArch64, then the syndrome value is reported in ESR_EL1.
When the delegated SError exception injected using SCR_EL3.DSE is deferred by an ESB instruction, then the syndrome value is written to VDISR_EL3.
This register is present only when FEAT_E3DSE is implemented. Otherwise, direct accesses to VSESR_EL3 are UNDEFINED.
VSESR_EL3 is a 64-bit register.

When a delegated SError exception triggered by SCR_EL3.DSE is taken to EL2 or EL1 using AArch64, ESR_ELx[24] is set to VSESR_EL3.IDS.
When a delegated SError exception triggered by SCR_EL3.DSE is deferred by an ESB instruction, VDISR_EL3[24] is set to VSESR_EL3.IDS.
The reset behavior of this field is:
When a delegated SError exception triggered by SCR_EL3.DSE is taken to EL2 or EL1 using AArch64, ESR_ELx[23:0] is set to VSESR_EL3.ISS.
When a delegated SError exception triggered by SCR_EL3.DSE is deferred by an ESB instruction, VDISR_EL3[23:0] is set to VSESR_EL3.ISS.
The reset behavior of this field is:
