Operation mode
Normal mode
User boot mode
This device has two operation modes including the mode not to use the internal flash memory.
Among the flash memory operation modes listed in the above table, the User Boot mode is the
programmable modes. This mode is referred to as "Onboard Programming" modes where onboard
rewriting of internal flash memory can be made on the user's card.
After reset is cleared, it starts up from the internal flash memory.
In this operation mode, two different modes, i.e., the mode to execute user application programs and the
mode to rewrite the flash memory onboard the user’s card, are defined. The former is referred to as
"normal mode" and the latter "user boot mode."
The user can uniquely configure the system to switch between these two modes.
For example, the user can freely design the system such that the normal mode is selected when the port
"00" is set to "1" and the user boot mode is selected when it is set to "0."
The user should prepare a routine as part of the application program to make the decision on the
selection of the modes.
