6.8 Changes from the CC2564B Device to the CC2564C Device
The CC2564C device includes the following changes:
• Support added for standard HCI command for WBS to replace HCI VS command sequence
– Part of the Core Specification Addendum 2 (CSA2)
• Easy PCM interface integration when using both WBS (16 kHz) and NBS (8 kHz)
• PLC support added for NBS (8 kHz) when working at 16-kHz PCM clock
• Option added to start and stop the PCM clock as master on the PCM bus even when voice call is not
active or set a timer to extend the clock after voice or audio is removed
• Link layer topology support—Acts concurrently as peripheral and central low-energy device
• AFH algorithm enhancements—Improvements to the automatic frequency hopping algorithms
