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
Omap: protect Omap pad if you don't
use it.(1)

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