• Manufacturer Part Number: bc41b143a07
• Description: Single Chip Bluetooth
• Manufacturer: ETC-unknow

As with Long Frame Sync, BlueCore4-ROM samples PCM_IN on the falling edge of PCM_CLK and transmits
PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK
in the LSB position or on the rising edge.
9.7.4
More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO connections
can be carried over any of the first four slots.
9.7.5
BlueCore4-ROM is compatible with the General Circuit Interface (GCI), a standard synchronous 2B+D ISDN timing
interface. The two 64kbits/s B channels can be accessed when this mode is configured.
