rt 1 on the Zircon PM. The 1.1V (MPC744X core
oltage), 2.5V, 3.3V, 5V and other supply voltages are connected to A/D input ports
on the Zircon PM through precision voltage-divider networks. These connections
(see Table 23 and Table 24) allow remote monitoring of the temperatures and
voltages on the HW400c/2 by a system management device (shelf manager).
