21.1.5
Programming/erasing is executed by downloading the on-chip program to the on-chip RAM and
specifying the program address/data and erase block by using the interface register/parameter.
The procedure program is made by the user in user program mode and user boot mode. An
overview of the procedure is given as follows. For details, see section 21.4.2, User Program Mode.
1. Selection of on-chip program to be downloaded

For programming/erasing execution, the FLSHE bit must be set to 1 to transition to user
program mode.
This LSI has programming/erasing programs which can be downloaded to the on-chip RAM.
The on-chip program to be downloaded is selected by setting the corresponding bits in the
programming/erasing interface register. The address of the programming destination is
specified by the FTDAR.
