DESCRIPTION
Conversion value of Rid resistor
000: 0 ohms
001: 75 ohms
010: 102K ohms
011: 200K ohms
100: 440K ohms
101: ID floating
111: Error
Note:
Automatically asserted by the USB3320 when the
Rid Conversion is finished. The conversion will take
282uS. This bit will auto clear when the RidValue is
read from the Rid Conversion Register. Reading the
RidValue from the
not clear either RidConversionDone status bit.
Note:
Read only, 0.
DESCRIPTION
Asserted if the state of the ID pin changes from non-
floating to floating while the IdFloatRise bit is enabled
or if the state of the ID pin changes from floating to
non-floating while the IdFloatFall bit is enabled.
Not Implemented. Reads as 0b.
Not Implemented. Reads as 0b.
If RidIntEn is set and the state of the
RidConversionDone bit changes from a 0 to 1 this bit
will be asserted.
Read only, 0.
RidValue can also be read from the Vendor
Rid Conversion register described in
