(1-B) Method 2: Transferring a Programming Routine from an External Host
and the I/O bus to be used to transfer new program code. Create hardware and software accordingly.
Before installing the TMPM333FDFG/FYFG/FWFG on a printed circuit board, write the following
program routines into an arbitrary flash block using programming equipment.
Determine the conditions (e.g., pin states) required for the flash memory to enter User Boot mode
Also, prepare a programming routine shown below on the host controller:
Step-1
(a) Mode judgment routine: Code to determine whether or not to switch to User Boot mode
(b) Transfer routine:
(c) Programming routine:
