Description | Global Debug LSP MUX Register - Host This register is for internal use only. If DWC_USB3_PRESERVE_LOGIC_ANALYZER_SELECT is enabled during core configuration, then the default values readout is X (Undefined). Bit Bash test should not be done on this debug register. |

logic_analyzer_trace | 23:16 | rwNormal read/write | 0x3F | logic_analyzer_trace Port MUX Select Currently only bits[21:16] are used. For details on how the mux controls the debug traces, refer to the assign logic_analyzer_trace = code section in the DWC_usb3.v file. A value of 6h3F drives 0s on the logic_analyzer_trace signal. If you plan to OR (instead using a mux) this signal with other trace signals in your system to generate a common trace signal, you can use this feature. |
Reserved | 15:14 | roRead-only | 0x0 | Reserved |
HOSTSELECT | 13:0 | rwNormal read/write | 0x0 | Device LSP Select Selects the LSP debug information presented in the GDBGLSP register in host mode. |

Alternate Register Field: logic_analyzer_trace Offset=16 Width=8 read-write
[[*]] Description: Logic Analyzer Trace Port MUX Select
Currently only bits[21:16] are used. For details on how the mux controls the debug traces, refer to 'assign logic_analyzer_trace =' code section in the DWC_usb3.v file.
A value of 6'h3F drives '0's on the logic_analyzer_trace signal. If you plan to OR (instead using a mux) this signal with other trace signals in your system to generate a common trace signal, you can use this feature.
