2.14.2 Stop Mode Set-Up
Settings and operation for entering stop mode are described here.

As this register becomes setting mentioned above when
operating with X
the user does not need to set it again.
(When operating with X
(1) Enables the interrupt used for returning from stop mode.
(2) Sets the interrupt enable flag (I flag) to “1”.
(3) Clearing the protection and setting all clock stop control bit to “1” stops oscillation and causes
