I/O Supply
The device STA2500D has two different I/O supplies: BT_VIO_A and BT_VIO_B.
The two different pins may be potentially connected to separate dedicated voltage supplies
in order to harmonize the digital levels to the platform.
They are linked to different interfaces as described in Table 15.

In order to get other SPI modes, the Host must send a specific configuration at start-up in addition of these configuration
pins.
