Trigger
External events transition AIROC™ CYW43012 Wi-Fi &
Bluetooth® combo chip out of reset; either BT_REG_ON or
WL_REG_ON pulled HIGH by PSoC™ 6 MCU.
AIROC™ CYW43012 Wi-Fi & Bluetooth® combo chip enters DS0
mode; managed by on-chip PMU and requires enabling power
save in the device
External events or PMU transitions AIROC™ CYW43012 Wi-Fi &
Bluetooth® combo chip to active mode; possible PSoC™ 6 MCU
actions:
BT_DEV_WAKE
•
SDIO interrupt
•
External events transition AIROC™ CYW43012 Wi-Fi &
Bluetooth® combo chip to reset state; both WL_REG_ON and
BT_REG_ON are pulled LOW by PSoC™ 6 MCU.
