18.6 Flash Memory On-Board Programming Modes
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
18.6. For a diagram of the transitions to the various flash memory modes, see figure 18.2.

Notes: 1. (1) For the high-level application timing, see Notes on Use of Boot Mode.
(2) In boot mode, the inverse of the MD setting should be input.

(3) In boot mode, the mode control register (MDCR) can be used to monitor the status
of modes 5, 6, and 7, in the same way as in normal mode.
2. Never apply 12 V to the H8/3048F-ONE (single power supply). If do so, the LSI will be
permanently damaged.
3. For pins RXD1 and TXD1, use on-board pull-up.
