Reset
Normal
Deep Power-Down
Assertion of the RSTIN# signal sets the device in Reset mode.
During power-up, boot detector circuitry sets the device in Reset mode.
A valid write sequence to Mobile DiskOnChip Plus sets the device in Normal mode. This is
done automatically by the TrueFFS driver on power-up (reset sequence end).
Switching back from Normal mode to Reset mode can be done by a valid write sequence to
Mobile DiskOnChip Plus, or by triggering the boot detector circuitry (by soft reset).
Power-down.
A valid write sequence, initiated by software, sets the device from Normal mode to Deep
Power-Down mode. Four read cycles from offset 0x1FFF set the device back to Normal mode.
Alternately, the device can be set back to Normal mode with an extended access time during a
read from the Programmable Boot Block (see Section 10.4.1 for read cycle timing).
Asserting the RSTIN# signal and holding it in this state while in Normal mode puts the device
in Deep Power-Down mode. When the RSTIN# signal is released, the device is set in Reset
mode.
