cations where a relatively short program is executed repeatedly at periodic intervals. This periodic sig-
nal (for example, a clock from a low-power consumption oscillator) is input to the STOP pin. In the
edge-sensitive release mode, STOP mode is started even when the STOP pin input is high level. Do
not use any STOP5 to STOP2 pin inputs for releasing STOP mode in edge-sensitive release mode.
Note 1: Even if the STOP pin input is low after warm-up start, the STOP mode is not restarted.
Note 2: In this case of changing to the level-sensitive mode from the edge-sensitive mode, the release mode
In this mode, STOP mode is released by a rising edge of the STOP pin input. This is used in appli-
Edge-sensitive release mode (RELM = “0”)
