Section 27 Power-Down Modes
This LSI supports sleep mode, software standby mode, deep standby mode, and module standby
mode. In power-down modes, functions of CPU, clocks, on-chip memory, or part of on-chip
peripheral modules are halted or the power-supply is turned off, through which low power
consumption is achieved. These modes are canceled by a reset or interrupt.
