When pins are set to on-board programming mode, 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
17.30. For a diagram of the transitions to the various flash memory modes, see figure 17.34.
