If the link requires a 6-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1507D1 to 6-pin serial mode. In 6-pin serial mode, the
DATA[7:0] bus definition changes to that shown in
link sets the 6PIN_FSLS_SERIAL bit in the INTF_CTRL register (see
logic 1. To exit 6-pin serial mode, the link asserts STP. This is provided primarily for links
that contain legacy full-speed or low-speed functionality, providing a more cost-effective
upgrade path to high-speed. An interrupt pin is also provided to inform the link of USB
events. If the link requires CLOCK to be running during 6-pin serial mode, the
CLOCK_SUSPENDM register bit must be set to logic 1.
For more information on 6-pin serial mode enter and exit protocols, refer to UTMI+ Low
Pin Interface (ULPI) Specification Rev. 1.1.
If the link requires a 3-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1507D1 to 3-pin serial mode. In 3-pin serial mode, the data
bus definition changes to that shown in
the 3PIN_FSLS_SERIAL bit in the INTF_CTRL register (see
exit 3-pin serial mode, the link asserts STP. This is primarily provided for links that contain
legacy full-speed or low-speed functionality, providing a more cost-effective upgrade path
to high-speed. An interrupt pin is also provided to inform the link of USB events. If the link
requires CLOCK to be running during 3-pin serial mode, the CLOCK_SUSPENDM
register bit must be set to logic 1.
