6Pin FS/LS Serial Mode
Six pin serial mode utilizes the data bus pins for the serial functions shown in
The USB3320 includes Carkit Mode to support a USB UART and USB Audio Mode.
By entering Carkit Mode, the USB3320 current drain is minimized. When operating in
Mode (60MHz REFCLK
configure the 60MHz clock to continue by setting the ClockSuspendM bit of the
register before entering Carkit Mode. If set, the 60 MHz clock will continue during the Carkit Mode of
operation.
In Carkit Mode, interrupts are possible if they have been enabled in the
The state of each interrupt source is sampled prior to the assertion of DIR and this is compared against
the asynchronous level from interrupt source. In Carkit Mode, the Linestate signals are not available
per the ULPI specification.
Exiting Carkit Mode is the same as exiting Low Power Mode as described in
must assert STP to signal the transceiver to exit serial mode. When the transceiver can accept a
command, DIR is de-asserted and the transceiver will wait until the Link de-asserts STP to resume
synchronous ULPI operation. The RESETB pin can also be pulsed low to reset the USB3320 and
return it to Synchronous Mode.
