Bit Name R/W Default Description
6 Remote Diode 1 R 0 The LM96000 automatically sets this bit to 1 when there is either a short or open
Fault circuit fault on the Remote1+ or Remote1− thermal diode input pins. A diode fault will
also set bit 4, Diode 1 Zone Limit bit, of Interrupt Status Register 1.
7 Remote Diode 2 R 0 The LM96000 automatically sets this bit to 1 when there is either a short or open
Fault circuit fault on the Remote2+ or Remote2− thermal diode input pins. A diode fault will
also set bit 6, Diode 2 Zone Limit bit, of Interrupt Status Register 1.

The VID register contains the values of LM96000 VID0–VID4 input pins. This register indicates the status of the
VID lines that interconnect the processor to the Voltage Regulator Module (VRM). Software uses the information
in this register to determine the voltage that the processor is designed to operate at. With this information,
software can then dynamically determine the correct values to place in the VCCP Low Limit and VCCP High
Limit registers.
This register is read only — a write to this register has no effect.

Limit
If a voltage input either exceeds the value set in the voltage high limit register or falls below the value set in the
voltage low limit register, the corresponding bit will be set automatically by the LM96000 in the interrupt status
registers (41-42h). Voltages are presented in the registers at ¾ full scale for the nominal voltage, meaning that at
nominal voltage, each input will be C0h, as shown in Table 2.
Setting the Ready/Lock/Start/Override register Lock bit has no effect on these registers.
