User Boot Mode
Determine the conditions (e.g., pin states) required for the flash memory to enter User Boot mode and
the I/O bus to be used to transfer new program code. Create hardware and software accordingly. Before
installing the TMPM370 on a printed circuit board, write the following program routines into an arbitrary
flash block using programming equipment.
After
User Boot mode. If mode switching conditions are met, the flash memory enters User Boot mode. (All
interrupts including NMI must be disabled while in User Boot mode.)

(a) Mode judgment routine: Code to determine whether or not to switch to User Boot mode
(b) Programming routine: Code to download new program code from a host controller and
(c) Copy routine: Code to copy the data described in (b) from the TMPM370 flash memory to either
