9.5.2. ETB resets

ATRESETn resets all of the ETB registers in the ATCLK domain. ATRESETn must be synchronized externally in the CoreSight infrastructure by a global CoreSight reset signal that asserts ATRESETn asynchronously and deasserts ATRESETn synchronously with ATCLK.

PRESETDBGn resets the APB interface of the ETB. PRESETDBGn must be synchronized externally in the CoreSight infrastructure by a global CoreSight reset signal that asserts PRESETDBGn asynchronously and deasserts PRESETDBGn synchronously with PCLKDBG.
