Table 23A-1 shows the internal state of the LSI in the respective modes. Table 23A-2 shows the
conditions for shifting between the low power dissipation modes.
Figure 23A-1 is a mode transition diagram.

Note:
“Halted (retained)” means that internal register values are retained. The internal state is
“operation suspended.”
“Halted (reset)” means that internal register values and internal states are initialized.
In module stop mode, only modules for which a stop setting has been made are halted
(reset or retained).
