The Hailo 15 uses some GPIO signals for its internal controls. Some of the signals are of the CPU and others are of the IO Expender. The following table describes the GPIO allocation.
Signal | I/O | Description | Remarks |
H_GPIO_6 | H_GPIO_6 | Reset the IO Expander | Active Low |
H_GPIO_8 | H_GPIO_8 | IO Expander interrupt | Active Low |
WL_REG_ON | IO_EXP 0-1 | Enable the WIFI radio | Active High |
BT_REG_ON | IO_EXP 0-2 | Enable the BT radio | Active High |
ETH_RST# | IO_EXP 0-3 | Reset the Ethernet PHY | Active Low |
ENET_nINT | IO_EXP 0-4 | Ethernet PHY interrupt | Active Low |
QSPI_SEL | IO_EXP 0-4] | Select the QSPI interface | “0” FLASH memory “1” Board to Board conn. |
