Field Name Bits Default Description
DATA_REGISTER 31:0 0x0 This register is used to force a flush of the PVS block
when single-buffered updates are performed. The multi-
state control of PVS Code and Const memories by the
driver is primarily for more flexible PVS state control
and for performance testing. When this register address
is written, the State Block will force a flush of PVS
processing so that both versions of PVS state are
available before updates are processed. This register is
write only, and the data that is written is unused.
