In addition to its normal operating state, the flash memory has power-down states in which power
consumption is reduced by halting part or all of the internal power supply circuitry.
There are three flash memory operating states:
(1) Normal operating mode: The flash memory can be read and written to.
(2) Power-down mode: Part of the power supply circuitry is halted, and the flash memory can be
(3) Standby mode: All flash memory circuits are halted, and the flash memory cannot be read or
States (2) and (3) are flash memory power-down states. Table 19.22 shows the correspondence
between the operating states of the LSI and the flash memory.
Table 19.22 Flash Memory Operating States
19.12.1 Note on Power-Down States
When the flash memory is in a power-down state, part or all of the internal power supply circuitry
is halted. Therefore, a power supply circuit stabilization period must be provided when returning
to normal operation. When the flash memory returns to its normal operating state from a power-
down state, bits STS2 to STS0 in SBYCR must be set to provide a wait time of at least 20 µs
(power supply stabilization time), even if an oscillation stabilization period is not necessary.
