16.5.7 Bit Buffer Registers

Thirty-two addresses correlate to bit buffer functions. The Buf Word 0 (LW0) Register through the Buf
Word 31 (LW7) Register are used as the eight long words (LW0 through LW7) in the Bit Buffer
Sub-Module. The registers access the portions of the long words shown in Figure 16-4 on page 16-12.

16.5.7.1 Buffer Word Registers

The BTA keeps track of the most recently accessed long word accessed by the BTA. The Bluetooth
software polls the BTA status (BUF_ADDR bit of the Status Register) to avoid Bit Buffer overrun or
underrun.
The Buf Word 0 (LW0) Register to Buf Word 31 (LW7) Register bits are explained in Table 16-48.
