Section 19 ROM (Preliminary)
Bit 3—Flash Memory Control Register Enable (FLSHE): Controls CPU access to the flash
memory control registers (FLMCR1, FLMCR2, EBR1, and EBR2). Setting the FLSHE bit to 1
enables read/write access to the flash memory control registers. If FLSHE is cleared to 0, the flash
memory control registers are deselected. In this case, the flash memory control register contents
are retained.

19.6
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
19.6. For a diagram of the transitions to the various flash memory modes, see figure 19.2.
