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 TMPM330 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).
(1-B) Method 2: Transferring a Programming Routine from an External Host
(Step-1)
(Step-2)
(a) Mode judgment routine: Code to determine whether or not to switch to User Boot mode
(b) Transfer routine: Code to download new program code from a host controller
Also, prepare a programming routine shown below on the host controller:
(c) Programming routine: Code to download new program code from an external host controller and
