UniStone
PBA 31308
Each channel has its own frame signal (PCMFR1/PCMFR2) that indicates where in the frame the channel starts.
The Frame Signal Length is programmable. The start position of PCMFR2 in the frame is also programmable
(Channel 2 Start Position). PCMFR1 always starts at the beginning of the frame.
In frame master mode, UniStone generates PCMFR1 and PCMFR2. In frame slave mode the signal PCMFR1
is an input to UniStone and has to be supplied externally. PCMFR2 is still generated by UniStone. When only one
channel is used PCMFR2 can be switched off with the HCI command HCI_Infineon_Write_PCM_Mode.
In UniStone the second PCM channel cannot be used. The on-module bluetooth controller can handle two PCM
channels but due to restrictions in the controller pinout the second PCM channel cannot be supported when using
EEPROM.
