DTMF generator



External interrupt 1

3 independent channels (selectable edge, interrupt vector, source flag)

Rising/falling/both edges selectable

Used also for wake-up from the stop/sleep mode.

(Edge detection is also permitted in the stop mode.)

External interrupt 2

(wake-up)

8 independent channels (“L” level interrupt)

Used also for wake-up from the stop/sleep mode.

(Edge detection is also permitted in the stop mode.)

Standby mode

Sleep mode, stop mode
