TMS570LS3137: Data portion of DJZ instruction

sreenivasan m

Part Number: TMS570LS3137

Hi Team,

We are using DJZ instruction in our HET application micro code and after DJZ instruction, we would like to read the data field of DJZ. Can we read the data field of DJZ instruction?
The reason is that when we perform the read operation, we are struck and not able to perform the frequency measurement.

L06 MCMP { next=L07,cond_addr=L08,pin=0,order=DATA_GE_REG,reg=R,data=211};
L07 DJZ { next=L09,cond_addr=L09,reg=NONE};
L08 ADCNST { next=L09,remote=L07,min_off=0,data=1};

L09 ADD { src1=REM,src2=ZERO,dest=IMM,next=L10,remote=L08,data=0};

Hi Sahin,

...

L06 MCMP { next=L07,cond_addr=L08,pin=0,order=DATA_GE_REG,reg=R,data=611};
L07 DJZ { next=L09,cond_addr=L09,reg=NONE};
L08 ADCNST { next=L09,remote=L07,min_off=0,data=1};

L10 MCMP { next=L12,cond_addr=L11,pin=0,order=REG_GE_DATA,reg=R,data=10};

Event with MOV32 from data field of DJZ didnt worked for me. May be an example code which does the read of data field of DJZ instruction can help.

Hello,

The DJZ is the 8th instruction in your code. You can use following example code to read the data field of DJZ:

adc = hetRAM->Instruction[8].Data;
