CCS/TMS570LS1224: Delay from N2HET

Hello Yash,

You can use an ECMP instruction to generate an interrupt every xus, and also generate pulse output just to verify the periodic timing.

For example:

L00 CNT { reg=A,irq=OFF,max=20};
L01 ECMP { hr_lr=HIGH,en_pin_action=ON,pin=1,action=PULSEHI,reg=A,irq=ON,data=10};  //generate interrupt when register A=10
L02 BR { next=L00, cond_addr=L00, event=NOCOND};

If you don't need to verify the timing, an interrupt can also be generated directly from the CNT instruction's counter-overflow condition. The interrupt service routine can call the desired function. For example, 

L00 CNT { reg=A, max=1fh}  //generate interrupt when counter > 0x1f
L01 BR { next=L00, cond_addr=L00, event=NOCOND};

I don't have a ready example to share with you. Please refer to the N2HET chapter of TRM
