17.6
When pins are set to on-board programming mode and a reset-start is executed, a transition is
made to the on-board programming state in which program/erase/verify operations can be
performed on the on-chip flash memory. There are two on-board programming modes: boot mode
and user program mode. The pin settings for transition to each of these modes are shown in table
17.3. For a diagram of the transitions to the various flash memory modes, see figure 17.2.

17.6.1
When a reset-start is executed after the LSI's pins have been set to boot mode, the boot program
built into the LSI is started and the programming control program prepared in the host is serially
transmitted to the LSI via the SCI. In the LSI, the programming control program received via the
SCI is written into the programming control program area in on-chip RAM. After the transfer is
completed, control branches to the start address of the programming control program area and the
programming control program execution state is entered (flash memory programming is
performed). The system configuration in boot mode is shown in Figure 17.8.
