Section 23A Power-Down Modes [HD64F2636F, HD64F2638F, HD6432636F, HD6432638F,
HD64F2630F, HD6432630F, HD64F2635F, HD6432635F, HD6432634F]
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.

“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).
