19.6
There are two modes for programming/erasing of the flash memory; boot mode, which enables on-
board programming/erasing, and programmer mode, in which programming/erasing is performed
with a PROM programmer. On-board programming/erasing can also be performed in user
program mode. At reset-start in reset mode, this LSI changes to a mode depending on the MD pin
settings and FWP pin setting, as shown in table 19.3.
When changing to boot mode, the boot program built into this LSI is initiated. The boot program
transfers the programming control program from the externally connected host to on-chip RAM
via SCI3. After erasing the entire flash memory, the programming control program is executed.
This can be used for programming initial values in the on-board state or for a forcible return when
programming/erasing can no longer be done in user program mode. In user program mode,
individual blocks can be erased and programmed by branching to the user program/erase control
program prepared by the user.
