18.6 On-Board Programming Modes
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
18.5. For a diagram of the transitions to the various flash memory modes, see figure 18.2.
