Explanation

Pad: Connect to: Default peripheral (mode=0) Default function: Other available peripherals: Share with:
1 VIO 1V8 - Power 1v8 -
2 DC 5V - Power 5v -
3 MMC2_DAT7 MMC2_DAT7 Reset Wlan

MMC2_CLKIN(mode=1)

MMC3_DAT3(mode=3)

GPIO_139(mode=4)

Wlan: This pad can reset Wlan peripheral using Omap GPIO low level (GND). If you reset continuously Wlan all their pads are in High Impedance. Also you can disable Wlan from J990 low level.
Omap: protect Omap pad if you don't use it.(1)
5 MMC2_DAT6 MMC2_DAT6 Power down  Wlan

MMC2_DIR_CMD(mode=1)

MMC3_DAT2(mode=3)

GPIO_138(mode=4)

Wlan: This pad can power down Wlan peripheral using Omap GPIO low level (GND), power up removing GND. Also you can power down Wlan from J990 low level.
Omap: protect Omap pad if you don't use it.(1)
7 MMC2_DAT5 MMC2_DAT5 Reset Bluethoot

MMC2_DIR_DAT1(mode=1)

MMC3_DAT1(mode=3)

GPIO_137(mode=4)

Bluethoot: This pad can reset Bluethoot

peripheral using Omap GPIO low level (GND). If you reset continuously Bluethoot all their pads are in High Impedance. Also you can disable


Bluethoot from J990 low level.
Omap: protect Omap pad if you don't use it.(1)
9 MMC2_DAT4 MMC2_DAT4 -

MMC_DIR_DAT0(mode=1)

MMC3_DAT0(mode=3)

GPIO136(mode=4)

Wlan: Protect Wlan if you don' use it. See MMC2_DAT7 pad.
Omap: protect Omap pad if you don't use it.(1)
