Section 17 ROM
17.8
When pins are set to an on-board programming mode, they enter an on-board programming status
in which program, erase, and 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 17.14. For a diagram of the transitions to
the various flash memory modes, see figure 17.8.
