buses for flash memory program code on the old application and for serial I/O are different. It operates at the
single chip mode; therefore, a switch from normal mode in which user application is activated at the single chip
mode to User Boot Mode for programming flash is required. Specifically, add a mode judgment routine to a reset
program in the old application.
conformity with the user’s system setup condition. Also, flash memory programming routine that the user
uniquely makes up needs to be set in the new application. This routine is used for programming after being
switched to User Boot Mode. The execution of the programming routine must take place while it is stored in the
area other than the flash memory since the data in the internal flash memory cannot be read out during delete/
writing mode. Once re-programming is complete, it is recommended to protect relevant flash blocks from acci-
dental corruption during subsequent Single-Chip (Normal mode) operations. Be sure not to cause any exceptions
including a non-maskable while User Boot Mode.

Flash Memory (Rewrite/Erase)".

Before installing the TMPM333FDFG/FYFG/FWFG on a printed circuit board, write the following
program routines into an arbitrary flash block using programming equipment.
