RXACTIVE HIGH. In the search access code state, the baseband performs all ofthe tasks required to correlate with the access code from the receive data. When the baseband has correlated the access code, then it drives SYNCDETECT HIGH and makes PT8R1002 enter into receive payloatl state. During the pay- load, PT8R1002 eliminates any frequency offset between lo- cal and remote Bluetooth devices based on its measurement during syncword acquisition. PT8R1002 transmits demodu- lated data to the baseband at half frequency of DATACLK, which can be read by the baseband using appropriate timing recovery algorithm. The unidirectional interface is returns to the itlle state with the baseband driving RXACTIVE LO W after a fixed interval of TRxOfr
