;  TMS470 Demo -  HET PWM Sample Program
;
;  Program name :  HET_PWM_01_H.het associated with C program HET_PWM_01.c
;
;  This is a simple HET program that generate two PWMs of 25% and 50% duty cycle.
;  using the ECMP instruction to generate pulses on HET on CC0 and CC2 thus
;  lighting the corresponding LEDs.

; Implement a counter that uses register A and rolls over at 0x214A
L00: CNT  {next=L01, reg=A, irq=OFF, max=0x214A, data=0}

; PWM (50% duty cycle)
L01: ECMP {next=L02, reg=A, hr_lr=LOW, en_pin_action=ON, pin=CC0, action=PULSEHI, irq=Off, data=0x10A5}

; PWM (25% duty cycle)
L02: ECMP {next=L03, reg=A, hr_lr=LOW, en_pin_action=ON, pin=CC2, action=PULSEHI, irq=Off, data=0x852}

L03: BR	  {next=L00, cond_addr=L00, event=NOCOND}
