setting can be
Mode where
Initial value
0 : Stops transmission
1 : Output operation
0 : Positive logic (Low: Break interval; High: Make interval)
1 : Negative logic (Low:Make interval; High: Break interval)
0 : 10 pps
1 : 20 pps
Set the number of dial pulses to be transmitted.
Note: Before activating DPGEN0 (DPGEN0_EN = 1), be sure to set the following:
Note:
To activate DPGEN0, be sure to do so with TGEN0 and FSKGEN0 placed in a stop state. Using TGEN0,
FSKGEN0 and DPGEN0 concurrently is not allowed.

• After the above setting, set the primary/secondary function selection register (GPFA[0]) of GPIOA[0]
to “1”, and set to the secondary function (dial pulse output pin).
• Set the DPGEN0 output polarity control register (DPGEN0_POL).
By this setting, the output level (initial value) of the dial pulse output pin will be as follows:
When DPGEN0_POL = 0 (positive logic)
When DPGEN0_POL = 1 (negative logic)
