R_IRQ_FIFO_BL3
FIFO interrupt register for FIFO block 3
In HDLC mode the end of frame is signaled, while in transparent mode the frequency of
interrupts is set in the bitmap V_TRP_IRQ of the register A_CON_HDLC.
The bit value ’1’ indicates that the corresponding FIFO generated an interrupt. If a bit is
’0’, no interrupt occured in the corresponding FIFO.
Reading this register clears all set bits and the corresponding bit of the register R_IRQ_OVIEW.
