Epson ARM720T Manuel D’Utilisation

In Figure 11-15, SIZE_R2 sets the memory region size. The allowed values of SIZE_R2 are 

shown in Table 11-10. 

 

The encoding for SIZE_R2 is different from SIZE_C.

For the CAM read or write, RAM1 read or write, and RAM2 read or write operations, you must 

specify the index. The CAM and RAM1 operations use the value in the victim pointer, so you 

must write this before any CAM or RAM1 operation. RAM2 uses a pipelined version of the 

victim pointer used for the CAM or RAM1 operation. This means that to read from index N in 

the RAM2 array, you must first perform an access to index N in either the CAM or RAM1.
The write TLB lockdown operation is:

MCR p15, 0, <Rd>, c10, c0, 0
The write TLB lockdown format for Rd is shown in Figure 11-16.
