Processor VID status.
Reports the current state of the P1_VID5 through P1_VID0 pins. This
register will only be updated if P1_VID signals remain stable for at least
600 ns.
Reserved and will always report 0.
Processor VID status.
Reports the current state of the VID6 through VID0 pins. This register will
only be updated if VID signals remain stable for at least 600 ns.
Reserved and will always report 0.
Processor VID status. This mode is the recommended mode for support of
VRD11.
Reports the current state of the VID6 through VID0 pins. This register will
only be updated if VID signals remain stable for at least 600 ns.
Reserved and will always report 0.
Reserved and will always report 0.
Processor VID status. This mode is supplied for future experimentation and
will require additional hardware in order to support both VRD11 and VRD10
specifications.
Reports the current state of the VID7 through VID1 pins. This register will
only be updated if VID signals remain stable for at least 600 ns.
VID[5:0] for VRD 10 mode (functions same as LM93)
