3.3 Multicast Filtering

Multicast filtering is done within the hardware. On initialization, the multicast filter is disabled and all multicast frames are sent to the host. Once the device is initialized, multicast filtering is automatically enabled and the user can register for specific multicast addresses to begin receiving packets. Only frames from the registered addresses are filtered in, while all other multicast frames are dropped. The CC33xx software supports up to twenty different configurable multicast groups that can be configured. The multicast filter only works for the STA role, as the AP role should distribute all multicast frames to all other devices.
