"Onboard Programming" modes where onboard rewriting of internal flash memory can be made on the user's card.

This device has three 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 and the Single Boot mode
Either the Single Chip or Single Boot operation mode can be selected by externally setting the level of the BOOT

Operation mode
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 ex-
ample, the user can freely design the system such that the normal mode is selected when
the port "A0" 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.
After reset is cleared, it starts up from the internal Boot ROM (Mask ROM). In the Boot
ROM, an algorithm to enable flash memory rewriting on the user’s set through the serial
port of this device is programmed. By connecting to an external host computer through the
serial port, the internal flash memory can be programmed by transferring data in accordance
with predefined protocols.
