17.22.7 Programming/Erasing Interface
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. The
overview of the procedure is as follows. For details, see section 17.24.2, User Program Mode.
1. Selection of on-chip program to be downloaded and setting of download destination
This LSI has programming/erasing programs and they 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 download destination can be specified by
FTDAR.
