If the link requires a 3-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1507 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 INTF_CTRL register (see
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 UTMI+ Low
Pin Interface (ULPI) Specification Rev. 1.1 .
A Hi-Speed USB peripheral, host or OTG device handles more than one electrical state as
defined in Universal Serial Bus Specification Rev. 2.0 and On-The-Go Supplement to the
USB 2.0 Specification Rev. 1.3 . The ISP1507 accommodates various states through
register bit settings of XCVRSELECT[1:0], TERMSELECT, OPMODE[1:0],
DP_PULLDOWN and DM_PULLDOWN.
