Temporary masking an interrupt on Blackfin

Question asked by Mathieu on Dec 8, 2010

Hello all,

I'm using a BF533 ADSP and for a specific period of time, would like to mask an interrupt yet letting it latched if it occurs.

The thing is, as soon as the mask is disable, the Interrupt should be served if it has been latched when the mask was enable.

I searched through the BF Hardware Reference Manual and i think using the IMASK register could do so, but this is not clear to me wether the interrupt source is latched when an interrupt occurs.

Can anyone tell me the procedure to be followed ?

Thanks in advance.

Mathieu
