An application example of the DTMF generation circuit is shown in figure 18.5.

1. Setting the module stop mode
2. DTLR setting and system clock
3. Relationship between AVcc, AVss and Vcc, Vss
Note: If the conditions above are not met, the reliability of the device may be adversely affected.
It is possible to enable/disable the DTMF operation using the module stop control register. The
DTMF does not operate by the initial value of the register. The register can be accessed by
releasing the module stop mode. For more details, see section 22, Power-Down Modes.
When using the DTMF generation circuit, note the following: The DTLR must be set so as to
accommodate the system clock. If the DTLR setting does not match the system clock, correct
DTMF signal output frequency cannot be obtained.
Set AVss = Vss as the relationship between AVcc, AVss and Vcc, Vss. If the DTMF
generation circuit is not used, the AVcc and AVss pins must not be left open.
