Tex: longtable page break at specific rows only

Question

My table is logically divided by 2 rows in a group. I want the page break occurs only after the last row in the group. How I can do that with longtable? In the example below page break happens on "bit 6"

\documentclass[]{article}
\usepackage{longtable,booktabs}
\usepackage{geometry}
 \geometry{
 a4paper,
 total={160mm,257mm},
 left=10mm,
 top=20mm,
 }

\date{}

\begin{document}


\subsubsection{SOME\_REGISTER, 0x100}\label{some_register-0x100}

Some register for XXX

\begin{longtable}[c]{|p{0.15\textwidth}|p{0.4\textwidth}|p{0.15\textwidth}|p{0.15\textwidth}|p{0.2\textwidth}|}
\caption{A sample long table.} \label{tab:long} \\
\hline
{\bf Bit Position} & {\bf Field Name} & {\bf Permissions} & {\bf Reset Value} & {\bf Field Attributes} \\\hline 
\endfirsthead
\multicolumn{5}{c}%
{{\bfseries \tablename\ \thetable{} -- continued from previous page}} \\
\hline {\bf Bit Position} & {\bf Field Name} & {\bf Permissions} & {\bf Reset Value} & {\bf Field Attributes} \\ \hline 
\endhead
\hline \multicolumn{5}{|r|}{{Continued on next page}} \\ \hline
\endfoot

\hline \hline

\\*does not give you the desired result since it is followed by an \hline. Pagrebreaks are generally allowed at \hline. To change this, you can use the approach presented in https://tex.stackexchange.com/a/6353/134144 — leandriis, Mar 21 '20 at 12:10
Why use you \bf instead of \textbf{} text mode or \mathbf{} in math-mode? — Sebastiano, Mar 22 '20 at 12:37

You can use \\ to allow for pagebreaks after this specific row. Use \\* instead to disallow page breaks.

I tried it but it did not work - the page break occurs right after the \\* – Michael Mar 21 '20 at 10:54
Please edit your question and add a compilable example document that allows others to reproduce the issue you describe. – leandriis Mar 21 '20 at 10:58
