In user mode, the flash memory will operate in either of the following states:
• Normal operating mode
• Standby mode
• Power-down state
Table 17.8 shows the correspondence between the operating modes of this LSI and the flash
memory. When the flash memory returns to normal operation from a power-down state, a power
supply circuit stabilization period is needed. When the flash memory returns to its normal
operating state from watch mode or standby mode, bits STS2 to STS0 in SBYCR must be set to
provide a wait time of at least 100 μs; when returns from flash memory module stop mode, the
software wait state should be set.

The flash memory can be read when part of the power supply circuit is halted and the LSI
operates by subclocks.
