| Field Name | Bits | Type | Reset Value | Description |
|---|
| SWOUARTNRZ | 11 | roRead-only | 0x0 | Indicates whether Serial Wire Output (UART/NRZ) is supported. |
| SWOMAN | 10 | roRead-only | 0x0 | Indicates whether Serial Wire Output (Manchester) is supported. |
| TCLKDATA | 9 | roRead-only | 0x0 | Indicates whether trace clock + data is supported. |
| FIFOSIZE | 8:6 | roRead-only | 0x0 | FIFO size in powers of 2. |
| CLKRELAT | 5 | roRead-only | 0x0 | Indicates the relationship between atclk and traceclkin. |
| MUXNUM | 4:0 | roRead-only | 0x0 | Indicates the Hidden Level of Input multiplexing. When nonzero this value indicates the type/number of ATB multiplexing present on the input to the ATB. Currently only 0x00 is supported, that is, no multiplexing present.This value is used to assist topology detection of the ATB structure. |
