22.4.2 (1-B) Procedure that a Programming Routine is transferred from External Host
22.4.2.1 Step-1
A user determines the conditions (e.g., pin status) to enter the user boot mode and the I/O bus to be
used to transfer data. Then suitable circuit design and program are created. Before installing the device
on a printed circuit board, write the following two program routines into an arbitrary flash block using pro-
gramming equipment such as a flash writer.
(a) Mode determination routine:
A program to determine to switch to reprogramming operation
(b) Transfer routine:
A program to obtain a reprogramming program from the external device.
In addition, prepare a reprogramming routine shown below must be stored on the host controller.
(c) Reprogramming routine:
A program to reprogram data
