Section 21 Analog Front End Interface (AFEIF)
(2) Ringing Interrupt Timing
As the figure 21.3 shows, the ringing signal from the line is transformed to rectangular wave and
then input to AFEIF. The interrupt is generated at the rising edge of input wave in AFEIF module.
(3) Dial Pulse Interrupt Timing
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 21.3.3, DAA Interface about
dial pulse sequence.
