7.3
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 TEST
pin settings, NMI pin settings, and input level of each port, as shown in table 7.1. The input level
of each pin must be defined four states before the reset ends.
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 the 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.
