22 PWM_2 Output Programmable pulse width modulator port 2
24 PWM_3 Output Programmable pulse width modulator port 3
65 HPD_SRC Input General purpose input/output for HDMI cable hot plug detect.
Instantiates a start-up communication between source and sink HDMI devices.
Connected to GPIO_200.
84 BTN_N Input Connected to general purpose button on the expansion board.
Connected to GPIO_17.
57 I2C_0_SCL Output I
2
C port 0 clock
95 I2C_0_SDA Input/Output I
2
C port 0 data
25 ISH_GPIO_0 Input/Output ISH general purpose input/output 0
27 ISH_GPIO_1 Input/Output ISH general purpose input/output 1
32 ISH_GPIO_2 Input/Output ISH general purpose input/output 2
34 ISH_GPIO_3 Input/Output ISH general purpose input/output 3
29 ISH_GPIO_4 Input/Output ISH general purpose input/output 4
38 ISH_GPIO_5 Input/Output ISH general purpose input/output 5
31 ISH_GPIO_6 Input/Output ISH general purpose input/output 6
71 CLK_19P2M Output 19.2 MHz clock
69 OTG_EN Output General purpose input/output controlled by PMIC to enable the module to power a USB OTG device
9 PMIC_PWRBTN_N Input System power/sleep button input to PMIC; active low.
33 PMIC_PWRGOOD Output Notification to system that all cold boot voltage rails to power the system have ramped up. Transitions
high when module rails are within specification.
13 PMIC_RESET_N Input Notification to system that PMIC will respond to commands.
When asserted, the PMIC will not respond to SOC commands via I2C or SVID because of the PMIC being
either in standby or because a TLP is running. This is an active low signal.
79 SDCARD_CD_N Input SD card detect.
Active low when a card is present, pulled high with internal pull-up when card is not present.
75 SDCARD_CLK Output SD card clock
89 SDCARD_CMD Input/Output SD card command is used for card initialization and transfer of commands.
81 SDCARD_D0 Input/Output SD card data 0. By default, during power up or reset, only data 0 is used for data transfer.
83 SDCARD_D1 Input/Output SD card data 1
85 SDCARD_D2 Input/Output SD card data 2
87 SDCARD_D3 Input/Output SD card data 3
77 SDCARD_LVL_CLK_FB Input SD card clock feedback for aligning the SDIO data from the level shifter on-board the expansion board
via the controller. There is a loopback through the SD card level shifter that drives this pin.
90 SDCARD_LVL_CMD_DIR Output SD card command direction indicates whether host is transmitting or receiving over the command pin.
67 SDCARD_LVL_DAT_DIR Output SD card data direction indicates whether host is transmitting or receiving over the data.
88 SDCARD_LVL_SEL Output SD card level select performs the 1.8V to 3.0V negotiation.
91 SDCARD_PWR_DOWN_
N
Output SD card power down indicates to SDIO device to power down.
53 SPI_1_CLK Output SPI port 1 clock
63 SPI_1_MISO Input SPI port 1 receive data
55 SPI_1_FS0 Output SPI port 1 slave select 0
14 SPI_1_FS2 Output SPI port 1 slave select 2. Hardware strap with disable boot from SD card functionality.
51 SPI_1_MOSI Output SPI port 1 transmit data
93 UART_0_TXD Output UART port 0 transmit data. Hardware strap with reserved functionality.
Note: Goes with UART0 signals on other connector
26 UART_1_RXD Input UART port 1 receive data
28 UART_1_TXD Output UART port 1 transmit data. Hardware strap with disable boot from eMMC functionality.
20 USB2_ID_PMIC Input USB OTG ID for device attach/detach and USB ACA detection via detection of resistance connected to
pin. Connected to PMIC USBID pin.
8 USB2_0_DN Input/Output USB 2.0 port 0 data negative. Connected to PMIC USB 2.0 port 0.
6 USB2_0_DP Input/Output USB 2.0 port 0 data positive. Connected to PMIC USB 2.0 port 0.
