196 / 234 page ![]() CC2430 CC2430 PRELIMINARY Data Sheet (rev. 1.03) SWRS036A Page 196 of 232 14.34.8.10 LABEL Function: Set loop label Description: Sets next instruction as start of loop. If the current instruction is the last instruction in the instruction memory then the current PC is set as start of loop. Only one level of loops is supported. Operation: LABEL := PC+1 Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 1 0 1 0 14.34.8.11 RPT C Function: Conditional repeat Description: If condition C is true then jump to instruction defined by last LABEL instruction, i.e. jump to start of loop. If the condition is false or if a LABEL instruction has not been executed, then execution will continue from next instruction. The condition C may be negated by setting N=1 and is described in the table below. Condition code C Description Function 000 CCA is true CCA=1 001 Receiving packet SFD =1 010 CPU control true CSPCTRL.CPU_CTRL=1 011 End of instruction memory PC=23 100 Register X=0 X=0 101 Register Y=0 Y=0 110 Register Z=0 Z=0 111 Not used - Operation: PC := LABEL when (C xor N)=true PC := PC+1 when (C xor N) =false or LABEL=not set Opcode: 7 6 5 4 3 2 1 0 1 0 1 0 N C 14.34.8.12 SKIP S, C Function: Conditional skip instruction Description: If condition C is true then skip S instructions. The condition C may be negated (N=1) and is described in the table below (note same conditions as RPT C instruction). Condition code C Description Function 000 CCA is true CCA=1 001 Receiving packet SFD =1 010 CPU control true CSPCTRL.CPU_CTRL =1 011 End of instruction memory PC=23 100 Register X=0 X=0 101 Register Y=0 Y=0 110 Register Z=0 Z=0 111 Not used - Operation: PC := PC+S+1 when (C xor N)=true PC := PC+1 when (C xor N)=false Opcode: 7 6 5 4 3 2 1 0 0 S N C |
