RMAP Packet

Figure 1 - RMAP Packet Structure

Table 1 - RMAP Header

TYPE	RMAP packet type
	0x2000 - RMAP Read
	0x2001 - RMAP Write

Table 2 - RMAP Payload

RMAP_ADDR	Register address to read/write
RMAP_DATA	Register data to write, applicable to Write only. For Read, this field is unused

• For Host -> HW, we have both RMAP Read and Write types. RMAP Processor parses the Type field to initiate either a RMAP read or write cycle.
• For HW -> Host, we only have RMAP Read type e.g. read data content is fed back to Host.
• RMAP header is added by APP.
• Note, UDP port 1000 is used for RMAP packet. Packet Classifier forwards UDP port 1000 packets to RMAP Processor.
