In user mode, the flash memory will operate in either of the following states:
• Normal operating mode
• Power-down state
• Standby mode
Table 20.6 shows the correspondence between the operating modes of the H8S/2268 Group and
the flash memory. When the flash memory returns to its normal operating state from standby
mode, a period to stabilize the power supply circuits that were stopped 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.
