Data Tightly-Coupled Memory Control Register
| EN | TCM enable. When a TCM is disabled all accesses are made to the AXIM interface. 0 (EN_0): TCM disabled. 1 (EN_1): TCM enabled. |
| RMW | Read-Modify-Write (RMW) enable. Indicates that all writes to TCM, that are not the full width of the TCM RAM, use a RMW sequence. 0 (RMW_0): RMW disabled. 1 (RMW_1): RMW enabled. |
| RETEN | Retry phase enable. When enabled the processor guarantees to honor the retry output on the corresponding TCM interface, re-executing the instruction which carried out the TCM access. 0 (RETEN_0): Retry phase disabled. 1 (RETEN_1): Retry phase enabled. |
| SZ | TCM size. Indicates the size of the relevant TCM. 0 (SZ_0): No TCM implemented. 3 (SZ_3): 4KB. 4 (SZ_4): 8KB. 5 (SZ_5): 16KB. 6 (SZ_6): 32KB. 7 (SZ_7): 64KB. 8 (SZ_8): 128KB. 9 (SZ_9): 256KB. 10 (SZ_10): 512KB. 11 (SZ_11): 1MB. 12 (SZ_12): 2MB. 13 (SZ_13): 4MB. 14 (SZ_14): 8MB. 15 (SZ_15): 16MB. |
