20.3.1
To use boot mode, a user program for programming and erasing the flash memory must be
provided in advance on the host machine (which may be a personal computer). Serial
communication interface channel 1 is used in asynchronous mode. If the H8/3437F is placed in
boot mode, after it comes out of reset, a built-in boot program is activated. This program starts by
measuring the low period of data transmitted from the host and setting the bit rate register (BRR)
accordingly. The H8/3437F’s built-in serial communication interface (SCI) can then be used to
download the user program from the host machine. The user program is stored in on-chip RAM.
After the program has been stored, execution branches to address H'F7E0 in the on-chip RAM,
and the program stored on RAM is executed to program and erase the flash memory.

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 (MD
If the mode select bits of MDCR are now read, they will indicate mode 2 (MDS1 = 1,
MDS0 = 0).
