VCC2DET (VCC2 Detect)
Output
AL-01
VCC2DET is internally tied to V
the system logic that it must supply the specified dual-voltage
requirements to the V
voltage to the processor core, independent of the voltage
supplied to the I/O buffers on the V
VCC2DET Low, system logic should sample VCC2H/L# to
identify core voltage requirements.
VCC2DET always equals 0 and is never floated—even during
the three-state test mode.
