3.6.4. 2023459: Target range check for MAPC/MOVALL/VMAPP/VMOVP ignores bits[51:48] of RDbase field
Description
The ITS ignores bits[51:48] of the RDbase (target) field of MAPC/MOVALL/VMAPP/VMOVP commands.
Conditions
Target field [51:47] of the RDbase field are nonzero during a MAPC, MOVALL, VMAPP, or VMOVP command.
Impact
A command issued with an out-of-range target might not be detected, and it might execute with a truncated TGT field.
Workaround
Software should only use legal targets that only use the lower bits of the RDbase field.
