For details, refer to On-The-Go Supplement to the USB 2.0 Specification Rev. 1.3 .
The ISP1505 supports both 6-pin serial mode and 3-pin serial mode, controlled by
bits 6PIN_FSLS_SERIAL and 3PIN_FSLS_SERIAL of the Interface Control register. For
details, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1, Section 3.10 .
