Module dot15d4 

IEEE 802.15.4 (Zigbee / Dot15d4) protocol layer implementation.

Provides full 802.15.4 MAC frame parsing, building, and field access with:

• Frame Control Field (FCF) with all flag/mode fields
• Variable-length addressing (short and long addresses)
• PAN ID compression support
• Auxiliary Security Header (optional)
• Beacon frames with superframe spec, GTS, and pending addresses
• MAC command frames with all command payloads
• FCS (CRC-16 CCITT Kermit) computation and verification

All fields are little-endian as per the IEEE 802.15.4 standard.
