6.11
In user mode, the flash memory will operate in either of the following states:
• Normal operating mode
• Power-down operating mode
• Standby mode
Table 6.23 shows the correspondence between the operating modes of this LSI and the flash
memory. In subactive mode, the flash memory can be set to operate in power-down mode with the
PDWND bit in FLPWCR. When the flash memory returns to its normal operating state from
power-down mode or 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 SYSCR1 must be set to provide a wait time of at least 20 µs, even when the external
clock is being used.

The flash memory can be read and written to at high speed.
The power supply circuit of the flash memory is partly halted and can be read under low power
consumption.
All flash memory circuits are halted.
