| Field Name | Bits | Type | Reset Value | Description |
|---|
| No_fetch_cmp | 17 | roRead-only | 0x1 | No Fetch comparisons. Address comparators are not capable of performing fetch-stage comparisons. Setting bits [2:0] of an Address Access Type Register to b000 (instruction fetch) causes the comparator to have UNPREDICTABLE behavior. |
| No_of_sup_cores | 14:12 | roRead-only | 0x0 | Number of supported cores minus 1. The value given here is the maximum value that can be written to bits [27:25] of the Control Register. |
| Port_mode | 11 | roRead-only | 0x0 | Port mode supported. |
| Port_size | 10 | roRead-only | 0x0 | Port size supported. |
| Max_port_size_3 | 9 | roRead-only | 0x0 | Maximum port size[3]. This bit is used in conjunction with bits [2:0]. |
| Fifofull_support | 8 | roRead-only | 0x0 | If set to 1, FIFOFULL is supported. This bit is used in conjunction with bit [23] of the ETM Configuration Register. |
| Full_rate | 4 | roRead-only | 0x0 | Full-rate clocking is no longer supported. |
| Half_rate | 3 | roRead-only | 0x1 | All modes use half-rate clocking. |
| Max_port_size_2_0 | 2:0 | roRead-only | 0x4 | Maximum port size[2:0]. This bit is used in conjunction with bit [9]. |
