(2) Dial Pulse Sending Sequence
A dial pulse is generated according to the conditions that are specified in ACTR2, and is sent out
to AFE_RLYCNT.
As the basic clock for generating the dial pulse is AFE_FS that is input from AFE, it is necessary
to make AFE in operating state. An example of control sequence for dial pulse sending is shown
below.
Note that this sequence cannot be operated when RLYC bit (ACTR2) is low.
[Conditions]
Make ratio:
Pulse interval:
Minimum pause: 600 ms
Dial number:
[Control sequence]
1. Set PPS (ACTR2) → “1”, MKR → “9EH1”, MNRPCNT → “1680H”
2. Set DPNQ → “AF12H”.
3. Set RLYC → “H”. (Off Hook)
4. Detect dial tone or wait specific period. (Controlled by software)

1. First INT occur. RCEN (ACTR2) turns on.
2. From 2nd INT, read the RCNTV.
3. After acknowledge the ringing, RCEN (ACTR) turns off and goes
