cxxx

The Codes from c000 to c00f are compound codes, which can signal more then one state of the receiving number at once.

The last digit gives the hexadecimal value for four bits that can all be set or not set. c000 means none of them are set, c00f means all are set. To find out which ones are set one has to find a sum of basic values that is equal to the compound value. E.g. c003 means c002 and c001 is true (1+2=3), c00d means c001, c004 and c008 is true (8+4+1=13=D)
