It is allowed to become Shutdown state if all operations can be temporarily stopped, by BACI command or

HCI vender command. Sleep mode will suspend 26MHz clock in RF block, and be kept with 32.768KHz low power

clock from external pin till wakeup.

(Note) In the HCI Mode, the transition to the Long Interval State or Sleep State is not performed.

●Wakeup Factor

Wakeup Factor is necessary to return from Deep sleep mode or Application Sleep. Wakeup Factor, low state of GPIO1

pin or WAKEUP pin, will be detected, and RF block clock will start to oscillate.

●Current Profile

Following example shows current consumption and power state transition waking up from Deep sleep mode, perform

RX and TX and return to Deep sleep mode.
