Figure 7: Typical GML Commander Program for M0 File Transfers
Updating M1 Files using Manual Mode
When M1 files are updated using manual mode:
The GML Commander program updates the M1 variables, and then
issues the system bit variable SLC_M1_Update_Request.
Once the SLC program sees the request, it issues the M1 Update
Acknowledge bit when ready.
Once both bits are issued, the 1394 GMC Turbo system software
begins the update.
When the update is completed, the 1394 GMC Turbo resets the
SLC_M1_Update_Request.
The SLC waits for the M1 Update Request bit to reset and then clears
the M1 Update Acknowledge bit. The update is completed and the
SLC can copy the new data from the M1 file.
