6.22 Downloading to the Flash Memory Area
The emulator enables downloading to the external flash memory area. This function requires a
program for programming the flash memory (hereinafter referred to as a write module), a program
for erasing the flash memory (hereinafter referred to as an erase module), and the RAM area for
downloading and executing these modules.
Notes: 1. The write and erase modules must be prepared by the user.
2. This function is not available when the SH7047F, SH7144F, or SH7145F is in use. For
these MCUs, the [Loading flash memory] page shown in figure 6.65 will not be
displayed.
 Interface of the write and erase modules with the emulator firmware
The emulator firmware branches to the write and erase modules. The following conditions
must be satisfied if branching from the emulator firmware to the write and erase modules and
return from the write and erase modules to the emulator firmware are to be successful.
 The write and erase modules must be entirely written in assembly language.
 All values of general and control registers must be saved before the write or erase modules
are called and restored on return from the modules.
 Configure the write and erase modules so that execution returns to the origin of the call
after processing.
 The write and erase modules must be Motorola S-type files.
