5.2 Power Up/Down Sequence

The BT_EN is the main power enable pin including the WIFI_EN. All supplies should be

stable for a minimum of 10 μs before BT_EN is de-asserted (i.e, greater than VIL for

VIO). If VIO = 3.3V, then VDD_BLE, VDD_WLAN, and VIO shares the same 3.3V power

(see Figure 1, page 20).

Figure 1 Power Up/Down Sequence

5.3 Power ON Reset Time

Table 6, page 20 describes the Power ON reset time.

5.4 Unconditional Shutdown

The BT_EN is used for unconditional shutdown.
