As the figure 22.3 shows, the ringing signal from the line is transformed to rectangular wave and
then input to AFEIF. The interrupt is generated at the falling edge of input wave in AFEIF
module.
(3)
Dial pulse interrupt is generated in the dial pulse transmit sequence when AFEIF reads 0H (end)
data from DPNQ register or all of 4 digits are output. Refer to section 22.4.3, DAA Interface about
dial pulse sequence.
(4)
Interrupt is generated as is shown in figure 22.4. That is, AFEIFI signal is generated by
performing OR operation on the four signals from ASTR1 in FIFO interrupt control and the two
signals from ASTR2 in DAA interrupt control, and then sent out to INTC as one interrupt signal
(AFECI).
