DETECTION COMPARATORS
to generate associated interrupts, and sense and masking bits are available through SPI (refer to
thresholds are specified for the minimum detect levels, and bits can be used in combination to qualify a VBUS window. Events
are communicated via (INT pin) interrupts and managed through SPI registers to allow the application processor to turn off the
PHY.
connector. The power input is then brought into an end product on the VBUS pin of the USB connector. For fault condition
robustness, VBUS over-voltage protection is included to protect the system and flag an over-voltage situation to the processor
via the USBOVI interrupt.
ID DETECTOR
on the application. However, it is also supports two additional modes which are outside of the USB standards: a factory mode
and a non-USB accessory mode. The state of the ID detection can be read via the SPI to poll dedicated sense bits for a floating,
grounded, or factory mode condition on the UID pin. There are also dedicated maskable interrupts for each UID condition as well.
set low it is a resistor. ID100KPU switches in an additional pull-up from VCORE to UID (independent of IDPUCNTRL). The UID
voltage can be read out via the ADC channel ADIN7, see
custom vendor applications by evaluation of the ADIN7 conversion reading.

The ID detector is primarily used to determine if a mini-A or mini-B style plug has been inserted into a mini-AB style receptacle
The ID detector is based on an on-chip pull-up controlled by the IDPUCNTRL bit. If set high the pull-up is a current source, if
