If the link requires a 3-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1506 to 3-pin serial mode. In 3-pin serial mode, the data bus
definition changes to that shown in
3PIN_FSLS_SERIAL bit in the Interface Control register to logic 1. To 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.
For more information on 3-pin serial mode enter and exit protocols, refer to
