Timestamps are requested if the monitor’s CMB data set unit input data matches the value in the Monitor CMB timestamp pattern and mask registers (M_CMB_TPR and M_CMB_TPMR) when CMB timestamp enabled via the timestamp insertion enable register bit(CMB_TIER.PATT_TSENAB). The pattern match trigger output is achieved via setting values into the CMB trigger pattern and mask registers (CMB_XPR and CMB_XPMR). After configuring a pattern through these registers, the TPDM subunit will assert an output trigger every time it receives new input data that matches the configured pattern value. Values in a given bit number of the mask register correspond to the same bit number in the corresponding pattern register.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
