If "cc CONDITION" is true then there's generation of a level 7 exception, else execution continue normally. Immediate data is optional, if given, the exception sub-routine can use it. Condition code 'cc' specifies one of the following:
Bitmap | CC | Name | Flags | Bitmap | CC | Name | Flags |
---|---|---|---|---|---|---|---|
0000 | F | False | Z = 1 | 1000 | VC | oVerflow Clear | V = 0 |
0001 | T | True | Z = 0 | 1001 | VS | oVerflow Set | V = 1 |
0010 | HI | HIgh | C + Z = 0 | 1010 | PL | PLus | N = 0 |
0011 | LS | Low or Same | C + Z = 1 | 1011 | MI | MInus | N = 1 |
0100 | CC | Carry Clear | C = 0 | 1100 | GE | Greater or Equal | N (+) V = 0 |
0101 | CS | Carry Set | C = 1 | 1101 | LT | Less Than | N (+) V = 1 |
0110 | NE | Not Equal | Z = 0 | 1110 | GT | Greater Than | Z + (N (+) V) = 0 |
0111 | EQ | EQual | Z = 1 | 1111 | LE | Less or Equal | Z + (N (+) V) = 1 |
