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. 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 ALERT0 I Alert 0 Interrupt input for connection to the local companion (UPD360/UPD350) power delivery controller’s IRQ# signal. UPD_RESET_N O12 UPD360/UPD350 reset control output This output is used to controls the companion UPD360/UPD350’s RESET_N pin. DP1_VCONN1 I/O12 Port 1 VCONN1 enable DP1_VCONN2 I/O12 Port 1 VCONN2 enable |
