3.2.11. PROTOCOL_CFG
Summary:
Sets the chip up for specified protocol.
Purpose:
Command Stream
Reply Stream
Parameters:
PROTOCOL[7:0] - TODO
0 = Packet format is generic, no dynamic reprogramming of packet handler properties.
1 = Packet format is IEEE802.15.4g compliance. The following properties are overriden: PKT_CRC_CONFIG,
CRC_ENDIAN/BIT_ORDER in PKT_CONFG1 for TX and RX, PKT_FIELD_X_CRC_CONFIG for RX. Other
applicable properties in the packet handler group still need to be programmed. Field 1 should have the length of
16 bits to contain the PHR with PKT_LEN_FIELD_SOURCE set to 1 for RX. PSDU field shall use Field 2 with
variable length. Field 2 length should be set to the maximum allowed.
