On-Board Programming Mode

When pins are set to on-board programming mode and a power-on reset 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

22.6. For a diagram of the transitions to the various flash memory modes, see figure 22.2.
