22.4.1
AFE interface module generates 3 types of interrupt: FIFO data transfer, ringing detect, and dial
pulse transmit end. The timing of each interruption is described below.
(1)
Figure 22.2 shows interrupt timing of data transfer FIFO. Transmit FIFO generates the TFE and
THE interrupts after the last data is transfer red shift register. Receive FIFO generates the RFF and
RHF interrupt after the last data or specified word is transferred from shift register to FIFO.
