DESCRIPTION
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:
When this bit is asserted either through a register
write or set, the Rid converter will read the value of
the ID resistor. When the conversion is complete this
bit will auto clear.
This bit must remain at 0.
When enabled an interrupt will be generated on the
alt_int of the RXCMD byte when RidConversionDone
bit is asserted.
Note:
Read only, 0.
DESCRIPTION
Read only, 0.
When asserted, the DP and DM pins of the USB
transceiver are swapped. This bit can be used to
prevent crossing the DP/DM traces on the board. In
UART mode, it swaps the routing to the DP and DM
pins. In USB Audio Mode, it does not affect the
SPK_L and SPK_R pins.
Controls the output voltage of the VBAT to VDD33
regulator in UART mode. When the transceiver is
switched from USB mode to UART mode regulator
output will automatically change to the value
specified in this register when TxdEn is asserted.

set on the DP pin. (The pull-up is automatically
enabled in UART mode)

When in USB Audio Mode the regulator will
remain at 3.3V. When using this register it is
recommended that the Link exit UART
