2.8 Remapping Function
The remapping function replaces the addresses 0x0000 to 0x0FFF (initial boot area) in the program memory space with
the specified arbitrary 4 Kbyte area.
Figure 2-41 shows the general scheme of the remapping function.
The program can be started to execute at the area different from the initial boot area using the remapping function, that
enables updating(reprograming) the program code area including the initial boot area with the sefl-programming
function.
The remap function and IAP(In-Application Programming) program enable your application to reprogram the firmware.
Two ways are available to start the remap function.
(1)
Software Remap: Start remapping by reseting only the CPU after setting a remap address into the Flash Remap
Address Register (REMAPADD).
(2)
Code Option Remap:Start remapping at the system reset, available by setting the Code Option.
