Function
D[15..12]
RID[3:0]
This is the processor revision ID. 0x01 indicates the VR4102.
D[11..8]
MJREV[3..0]
Major revision number
D[7..4]
Reserved
Write 0 when writing. 0 is returned after a read.
D[3..0]
MNREV[3..0]
Minor revision number
This register is used to indicate revisions of the VR4102’s peripheral units.
The revision number is stored as a value in the form
y.x, where y is a major revision number and x is a minor
revision number.
Major revision number and minor revision number can distinguish the revision of the CPU and the peripheral
units, however there is no guarantee that changes to the CPU and the peripheral units will necessarily be reflected in
this register, or that changes to the revision number necessarily reflect real CPU’s and units’ changes. For this
reason, these values are not listed and software should not rely on the revision number in PREVIDREG to
characterize the units.
