Description
USB pull-up Controlled Output
VREF is used to control the USB D+ 1.5 k
The Vref output is in high impedance when the bit DETACH is set in the
USBCON register.
When the bit DETACH is reseted,
In low-power chips, the Vref output voltage is equal to the AVDD input.
In standard versions, the Vref output voltage is equal to the internal
regulator output.
