Note 1: Once warm-up starts, the device does not return to STOP mode even when the STOP pin input is pulled
Note 2: If RELM is changed to 1 (level mode) after being set to 0 (edge mode), STOP mode remains unchanged

is used in applications where a relatively short time of program processing is repeated at certain
fixed intervals. Apply a fixed-period signal (e.g., clock from the low-power oscillating source)
to the STOP pin. When RELM = 0 (edge mode), the device is placed in STOP mode even when
the STOP pin input level is high.

The device is released from STOP mode by a rising edge on STOP pin input. This method
