mode. In the automatic operation mode, flash memory data cannot be read and any commands stored in the
flash memory cannot be executed. In the automatic operation mode, any interrupt or exception generation
cannot set the device to the read mode except when a hardware reset is generated. During automatic operation,
be sure not to cause any exceptions other than reset and debug exceptions while a debug port is connected.
Any exception generation cannot set the device to the read mode except when a hardware reset is generated.

This flash memory device has the following two operation modes:
Transition to the automatic mode is made by executing a command sequence while it is in the memory read
Basic operation
set to the read mode immediately after power is applied, when CPU reset is removed, or when an
automatic operation is normally terminated. In order to return to the read mode from other modes or
after an automatic operation has been abnormally terminated, either the Read/reset command (a software
command to be described later) or a hardware reset is used. The device must also be in the read mode
when any command written on the flash memory is to be executed.

according to the address and data combinations applied (refer to Command Sequence).

will terminate the command execution and return to the read.
transmit command to the flash memory is called "bus write cycle." The bus write cycles are to be in a
specific sequential order and the flash memory will perform an automatic operation when the sequence
of the bus write cycle data and address of a command write operation is in accordance with a predefined
specific sequence. If any bus write cycle does not follow a predefined command write sequence, the
flash memory will terminate the command execution and return to the read mode.

・ The mode to automatically erase or rewrite memory data (Automatic operation)
Note 1: Command sequences are executed from outside the flash memory area.
Note 2: Each bus write cycle must be sequentially executed by 32-bit data transmit command. While

the flash memory to the read mode. Also, when a command that has not been completely written
has to be canceled, the Read/reset command must be used. The Read command is used to return

such an operation is made, it can result in an unexpected read access to the flash memory
and the command sequencer may not be able to correctly recognize the command. While
it could cause an abnormal termination of the command sequence, it is also possible that
the written command is incorrectly recognized.
When ID-Read command is used, the reading operation is terminated instead of automati-
