VREF
Allows you to choose whether to apply Vcc or an
external power supply to the MCU's pin VREF (43-
pin).
For the M38K09RFS and M38K29RFS, set this
switch to the Vcc side.
Allows you to choose whether to apply an external
power supply to the MCU's pin USBVREF (64-pin).
When the operating voltage of the MCU (Vcc) is
between 4.0 and 5.25 V, set switch SW2 to the NC
side.
When the operating voltage of the MCU (Vcc) is less
than 4.0 V, set switch SW2 to the TP5 side and apply
a voltage (3.0 to 3.6 V) to the TP5 (USBVREF).
Allows you to choose whether to apply an external
power supply or the VBUS of upstream to the VBUS
of USB downstream.
To use an external power supply, set switch SW3 to
the TP6 side and apply 5 V to the TP6 (DPVBUS).
To supply the VBUS of upstream, set switch SW3 to
the UPVBUS side. When the VBUS of upstream is
supplied, the VBUS of upstream is connected to the
VBUS of downstream. Therefore, do not apply a
voltage to the TP6 (DPVBUS).
