3.12 Bluetooth Accelerator
The Bluetooth Accelerator (BTA) radio interface supports the Motorola Radio, MC13180 using an SPI interface.
This section provides the data bus timing diagrams and SPI interface timing diagrams shown in Figure 38 and
Figure 39 on page 59, and the associated parameters shown in Table 24 and Table 25 on page 59.
