altera_avalon_fifo_read_fifo() not behaving as documented

I dont know if this is the right forum, but I am using "On-Chip FIFO Memory Core" using SOPC builder. Everything is good, but the altera_avalon_fifo_read_fifo() is not only returning the data correct...

Hi,

I would like to know why a function like

altera_avalon_fifo_clear_event() isn't available from an ISR?

Will iord_altera_avalon_fifo_event() generate an interrupt for example?

Do iord_altera_avalon_fifo_event() ,etc block waiting for some event to trigger?

I've discovered that all of the functions for the FIFO memory core aren't available from an ISR. So my next questions is, how can I access the FIFO event register from an ISR?

All suggestions welcomed
