isp1581 interrupt why

Hi all, I can't get ISP1581's interrupt output signal, plz help me!
I think I have configed all neccessary registers for interrupt signal output pin, such as GLINTEN bit of mode register,also the interrupt configure register & interrupt enable register, and I tried every trigger mode, but saddly the output is always high(high level trigger mode) or low(low level trigger mode), no pulse appears even when the BRESET and HS-STAT bits are set.
I'm waiting for your help, thank you so much!
 

Hi

What MSP430 are you using ?

Did you connect the inerrupt to port 1 or to port 2 ?

Did you configr the inerrupt pin to input ?


regards

Thanks for your reply
I solved the problem days ago, it's a low level mistake, I disable isp1581's GLINTEN bit when i use busWrite(MODE_REG0,SOFTCT), this function overwirte MODE_REG0's initial value.

I use MSP430F1611, config PxDIR as input, PxSEL as falling edge triggered, PxIE enable. The board works little well now, but now I'm facing a new problem. I will post a new topic here soon.

Thanks again
