This section details the power sequencing considerations for the MPC8360E/58E.
2.2.1
MPC8360E/58E does not require the core supply voltage (V
(GV
power supplies are stable and if the I/O voltages are supplied before the core voltage, there may be a period
of time that all input and output pins will actively be driven and cause contention and excessive current.
In order to avoid actively driving the I/O pins and to eliminate excessive current draw, apply the core
voltage (V
