Mode 2 is intended for systems where cache is in GPRAM mode. VIMS is retained with retention power to the GPRAM.
If software tries to put VIMS into cache mode after retention, the system fails because the TAG memory is corrupted.
The correct procedure is to put VIMS in off mode before VIMS is put in cache mode. For more details, see Figure 9-7.
