9.3.2.8 High-Speed Mode (HS)

For the two-wire bus to operate at frequencies above 400 kHz, the host device must issue an HS mode host code (00001XXX) as the first byte after a START condition to switch the bus to high-speed operation. The TMP1075 device does not acknowledge this byte, but it does switch the input filters on the SDA and SCL and the output filters on the SDA to operate in HS mode. After the HS mode host code is issued, the host transmits a two-wire device address to initiate a data transfer operation. The bus continues to operate in HS mode until a STOP condition occurs on the bus. Upon receiving the STOP condition, the TMP1075 switches the input and output filters back to fast-mode operation.
