1. DC_REQ will go low only if WLAN is the only core working. Otherwise if another core is working (e.g
BT) it will stay high.
2. CLK_REQ will go low only if WLAN is the only core working. Otherwise if another core is working and
using the Fref (e.g BT) it will stay high.
3. If WLAN is the only core that is operating, WL_EN must remain de-asserted for at least 64sec before
it is re-asserted.
