19.12 Power-Down States for Flash Memory
In user mode, the flash memory will operate in either of the following states:
• Normal operating mode
The flash memory can be read and written to.
• Standby mode
All flash memory circuits are halted.
Table 19.8 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, bits STS2 to STS0 in SBYCR must be set to provide a wait time of at least 100 µs,
even when the external clock is being used and an oscillation stabilization time is not necessary.
