SPI Interrupt

Question asked by frdca on Jun 24, 2013

Hello,

 

I have a problem in SPI. I am using BF531 in a personalized plate.

 

By unmasking the interrupt (SIC_IMASK = 0x2000) program now jumps to the interrupt routine and not out. Go out and back to routine.

 

If within the ISR I turn off SPI interrupt disappears, but soon turn back to the problem.

 

The interruption occurs before any settings, simply unmask the interrupt.

 

SPI_STAT equals 0x0001.

 

The CS pin is high. There is no clock on the SCK pin.

 

There is a flag that needs to be cleaned or initial setup?
