(Note 1) Command sequences are executed from outside the flash memory area.

command. While a command sequence is being executed, access to the flash
memory is prohibited. Also, don't generate any interrupt (except debug exceptions
when a Debugging probe is connected).If 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.
read mode prior to executing the command. Be sure to check before the first bus
write cycle that the FCFLCS RDY/BSY bit is set to "1." It is recommended to
subsequently execute a Read command.
perform a software reset to return to the read mode again.
A hardware reset is used to cancel the operational mode set by the command write
operation when forcibly termination during auto programming/ erasing or abnormal
termination during auto operations occurs. The flash memory has a reset input as the
memory block and it is connected to the CPU reset signal. Therefore, when the RESET
input pin of this device is set to “Low” level or when the CPU is reset due to any overflow of
the watch dog timer, the flash memory will return to the read mode terminating any
automatic operation that may be in progress. It should also be noted that applying a
hardware reset during an automatic operation can result in incorrect rewriting of data. In
such a case, be sure to perform the rewriting again.
Refer to Section 20.2.1 "Reset Operation" for CPU reset operations. After a given reset
input, the CPU will read the reset vector data from the flash memory and starts operation
after the reset is removed.
