This LSI has three types of the power-down modes: sleep mode, software standby mode, and
module standby function. In power-down mode, the CPU and some on-chip peripheral modules
are halted. The power-down mode is cancelled by reset or interrupt sources.
The power dissipation is decreased in addition by stopping a built-in regulator if internal circuit

13.1.1
This LSI supports the following power-down modes and function:
1. Sleep mode
2. Software standby mode
3. Module standby function (cache, X/Y memory, U memory, DMAC, UBC, H-UDI and on-chip
Note: * Also the USBH and USBF have the module standby function. However, the USBH and
Table 13.1 shows the transition conditions for entering the modes from the program execution
state, as well as the CPU and peripheral module states in each mode and the procedures for
canceling each mode.
On/off of a built-in regulator does not influence the operation of each mode.

Features
Power-Down Modes
USBF modules have control functions for their own since their clock sources are
different from those for other modules. For details, refer to section 18, USB Pin
Multiplex Controller (USBPM).
( = 1.5 V) is supplied from the external power supply.
