DS00002670C-page 19 USB7002 TABLE 3-6: PROGRAMMABLE FUNCTIONS DESCRIPTIONS Function Buffer Type Description Master SMBus/I2C Interface MSTR_I2C_CLK I/O12 Bridging Master SMBus/I2C controller clock (SMBus/I2C controller 1) MSTR_I2C_DATA I/O12 Bridging Master SMBus/I2C controller data (SMBus/I2C controller 1) Slave SMBus/I2C Interface SLV_I2C_CLK I/O12 Slave SMBus/I2C controller clock (SMBus/I2C controller 2) SLV_I2C_DATA I/O12 Slave SMBus/I2C controller data (SMBus/I2C controller 2) SPI Interface SPI_CLK I/O-U SPI clock. If the SPI interface is enabled, this pin must be driven low during reset. SPI_D[3:0] I/O-U SPI Data 3-0. If the SPI interface is enabled, these signals function as Data 3 through 0. SPI_CE_N I/O12 Active low SPI chip enable input. If the SPI interface is enabled, this pin must be driven high in powerdown states. UART Interface UART_TX O12 UART Transmit UART_RX I UART Receive UART_nCTS I UART Clear To Send UART_nRTS O12 UART Request To Send UART_nDCD I UART Data Carrier Detect UART_nDSR I UART Data Set Ready UART_nDTR O12 UART Data Terminal Ready I2S Interface I2S_SDI I I2S Serial Data In I2S_SDO O12 I2S Serial Data Out I2S_SCK O12 I2S Continuous Serial Clock I2S_LRCK O12 I2S Word Select / Left-Right Clock I2S_MCLK O12 I2S Master Clock MIC_DET I I2S Microphone Plug Detect 0 = No microphone plugged into the audio jack 1 = Microphone plugged into the audio jack Miscellaneous DP2_VCONN1 I/O12 Port 2 VCONN1 enable DP2_VCONN2 I/O12 Port 2 VCONN2 enable |
