CCS/TMS320F28379D: program instructions

Hi,

There are some registers which are EALLOW protected and CPU can only update these register after executing EALLOW instruction. After updating the register EDIS instruction is used to LOCK the access again.

IER is interrupt enable register so a write to this one is done to enable specific interrupt.

EINT instruction is for enabling the GLOBAL interrupt mask.

You need to refer C2000 workshop to get more familiar with this.

thank you Vivek
could you give some information about..
now i am doing programming for my controller to give 20Khz PWM for my converter switching.

so here i got some examples about ePWM....but i need to set the ISR-(interrupt service routine) for my application.

how can i set the ISR for 20Khz...

please some one help me.........

DINT is to disable the global interrupt - opposite of EINT.
I already explained about IER in my previous.
IFR is, interrupt flag status register. One can write into this register to generate the interrupt by SW.

Did you go through the workshop ?
