A.3 Notes

The following points should be noted when using the development support function.

When not using CD-ROM

To prevent program differences between when all files are on CD-ROM and when all debug files are present, the parent directory can be used even when CD-ROM is not used. The information of the local directory is added. Those automatically added directory information is set as a file on the CD-ROM.

Temporary access restriction method

If you normally access both memory files and DOS files, to temporarily stop DOS file access, set the target DIP switch to not use SCSI and reboot.
Conversely, to access only DOS files, set 0 to! Gfsd_mmc / GFMC_base.

Recommended file name access

While using a debug file, it is recommended to use file name access because the file identifier may change due to changes in the file structure.

Debug file directory information

Debug file directory information is set as follows.

Restrictions when using DOS files

DOS file retrieval parameters can be transferred only one sector at a time for convenience of processing. Setting the extraction parameter to a value other than 1 is invalid.

Restrictions on usable functions

When the transfer mode is GFS_TMODE_SCU, or when SCU-DMA is activated in the transfer function, only the following functions can be used until the transfer is completed.
】 A-Bus access is prohibited during SCU_DMA transfer, so other functions are prohibited.
