Functional description

5.2.3

OFF mode

In this mode, all internal oscillators are off. The supply voltage of the logic is lowered to

reduce the effect of leakage. The complete controller status is kept.

5.3

STBLC01 functional modes

5.3.1

State diagram

This part describes in which modes the STBLC01 can operate and how to switch from one

mode to another.

Figure 6 shows a simplified state diagram of the STBLC01. The arrows

indicate how the transaction from one state to the other can be achieved. Note that some

operations in some states are only allowed for HCI over SPI transport layer, some others

are achieved only by firmware.

As described in

Section 5.1, after this initial step, the STBLC01 automatically enters Idle

mode. Change of state is allowed through the HCI commands. In

Section 4.7 the time

required to switch from one state to the other is defined.
