The LDO_EN input level must be kept above the threshold voltage. After initial power-on, the LDO_EN signal can be held low to turn off the SV6158 or pulsed low to induce a subsequent reset. After LDO_EN is asserted, the host starts the power-on sequence of the UAW6158B. From that point, the typical UAW6158B power-on sequence is shown below:

After this signal has been de-asserted, the UAW6158B is in off mode waiting for host communication. Until then, the MAC, Baseband modem, and MCU subsystem blocks are powered off and all modules are held in reset. Once the host has initiated communication, the UAW6158B turns on its crystal and later on DPLL. After all clocks are stable and running, the resets to all blocks are automatically de-asserted. 4 Host Interface Timing Diagram. 4.1 SDIO Pin Description. The module supports SDIO version 2.0 for all 1.8V 4-bit UHSI speeds: SDR12(25 Mbps), and SDR25(50Mbps) in addition to the 3.3V default speed(25MHz) and high speed (50 MHz). It has the ability to stop the SDIO clock and map the interrupt signal into a GPIO pin. This out-of-band interrupt signal notifies the host when the WLAN device wants to turn on the SDIO interface. The ability to force the control of the gated clocks from within the WLAN chip is also provided.
