BitsTypeNameFunction
[31:1]--Reserved
[0]R/WTraceCaptEn

ETB Trace Capture Enable.

1 = enable trace capture

0 = disable trace capture.

This is the master enable bit forcing FtStopped HIGH when TraceCaptEn is LOW. When capture is disabled, any remaining data in the ATB formatter is stored to RAM. When all data is stored the formatter outputs FtStopped. Capture is fully disabled, or complete, when FtStopped goes HIGH. See ETB Formatter and Flush Status Register, FFSR, 0x300.
