Check the AP6256 datasheet for more information.
The module has signals that allow the host to control power consumption by enabling or disabling
the Bluetooth, WLAN and internal regulator blocks. These signals are described below.
Additionally, diagrams are provided to indicate proper sequencing of the signals for carious
operating states. The timing value indicated are minimum required values: longer delays are also
acceptable.
WL_REG_ON: Used by the PMU to power up or power down the internal regulators used
by the WLAN section. When this pin is high, the regulators are enabled and the WLAN
section is out of reset. When this pin is low the WLAN section is in reset
BT_REG_ON: Used by the PMU to power up or power down the internal regulators used
by the BT section. Low asserting reset for Bluetooth. This pin has no effect on WLAN and
does not control any PMU functions. This pin must be driven high or low (not left
floating)
