16.5.3 Bluetooth Pipeline Registers

Three registers control the units in the Bluetooth Pipeline.

16.5.3.1 HECCRC Control Register

The write-only HECCRC Control Register specifies the initialization word for the HEC and the CRC
checksum generation. The initialization word is derived from the Bluetooth clock, as described in the
Specification of the Bluetooth System, version 1.1. The HECCRC Control Register bits are described in
Table 16-25.
