USB3320 Transmitter
The USB3320 ULPI transmitter fully supports HS, FS, and LS transmit operations.
the high speed, full speed, and low speed transmitter block controlled by ULPI Protocol Block.
Encoding of the USB packet follows the bit-stuffing and NRZI outlined in the USB 2.0 specification.
Many of these functions are re-used between the HS and FS/LS transmitters. When using the

Table 5.1
LineState: These bits in the RXCMD byte reflect the current state of the Full-Speed single
ended receivers. LineState[0] directly reflects the current state of DP. LineState[1] directly
reflects the current state of DM. When DP=DM=0 this is called "Single Ended Zero" (SE0).
When DP=DM=1, this is called "Single Ended One" (SE1).

ENCODED UTMI EVENT SIGNALS
Set to the logic state of the ID pin. A logic low indicates an A device. A logic high
indicates a B device.
Asserted when a non-USB interrupt occurs. This bit is set when an unmasked event
occurs on any bit in the
