Configuration Option 3
Configuration Option 3 is used to monitor all the voltages in
the system for Processor 1 and Processor 2. Additional pins can
be configured for fan control, VIDs, or GPIOs, as required.
Features of Configuration Option 3 include the following:
Up to 13 different voltages monitored
Three +12V
+5V
+3.3V
+2.5V
+1.8V
Two +1.5V
Two +1.2V (VCCP1, VCCP2)
0.9V
VBATT
One local and one remote temperature channels
Up to three PWM drives and up to four TACH inputs
RESET I/O
Figure 6 shows the pin configuration when Configuration
Option 3 is chosen.
