19.3 On-Board Programming Modes
When an on-board programming mode is selected, the on-chip flash memory can be programmed,
erased, and verified. There are two on-board programming modes: boot mode, and user
programming mode. These modes are selected by inputs at the mode pins (MD₁ and MD₀) and
FV_PP pin. Table 19.7 indicates how to select the on-board programming modes. For details on
applying voltage V_PP, refer to section 19.7, Flash Memory Programming and Erasing Precautions
(5).

Note: * For details on the timing of 12 V application, see notes 6 to 8 in the Notes on Use of Boot
Mode at the end of this section.
In boot mode, the mode control register (MDCR) can be used to monitor the mode (mode 2
or 3) in the same way as in normal mode.
Example: Set the mode pins for mode 2 boot mode (MD₁ = 12 V, MD₀ = 0 V).
If the mode select bits of MDCR are now read, they will indicate mode 2 (MDS1 = 1,
MDS0 = 0).
