Register 0x224: RHDL Maximum Packet Length
This register configures the maximum legal HDLC packet byte length.
MAX[15:0]
The maximum HDLC packet length (MAX[15:0]) configures the FREEDM 32A1024L to reject
HDLC packets longer than a maximum size when LENCHK is set high. Receive packets with
total length, including address, control, information and FCS fields, greater than MAX[15:0]
bytes are aborted. When LENCHK is set low aborts are not generated regardless of packet
length and MAX[15:0] must be set to ‘hFFFF.
