| 49 | 49 | === Global Memory Map === |
| 50 | 50 | |
| 51 | | R3 global memory map is currently divided into 4 regions : Common control, Common Interrupt Control, Receiver and Transmitter. 65Kbytes are reserved for each region. The total number of address bits are 32-bit, but we will only use the lower 16-bits per region e.g. 65Kbytes per region. Therefore, bit31-28 are used for region address decoding between the individual regions as illustrated in figure 2. |
