Bits 2 to 0—Flash Memory Area Selection (RAM2 to RAM0): These bits are used together with bit 3 to select the
flash memory area to be overlapped with RAM. (See table 19-34.)

19.17 On-Board Programming Modes
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 19-35. For a diagram of the transitions to the various flash memory modes, see
figure 19-37.

Note: * Normally, user mode should be used. Set the SWE bit to 1 to make a transition to user program mode before
performing a program/erase/verify operation.
