Description
<4:0>
VID[4:0]
Read-Only
The VID[4:0] inputs from the CPU to indicate the expected processor core voltage. On
power-up, these bits reflect the state of the VID pins, even if monitoring is not enabled.
<7:5>
Reserved
Read-Only
Reserved for future use.

Setting the Configuration Register 1 lock bit has no effect on these registers.
High Limits: An interrupt is generated when a value exceeds its high limit ( > comparison).
Low Limits: An interrupt is generated when a value is equal to or below its low limit ( ?comparison).
