Reserved. Always 0.
26-16
RUN6P_RNG
Run Length 6+ Range. The number of runs of length 6 or more (for both 0 and 1) detected during entropy
generation must be greater than RUN6P_MAX - RUN6P_RNG, else a retry or error will occur. This
register is cleared to the default POR value by writing the TRNG0_MCTL[RST_DEF] bit to 1.

Reserved. Always 0.
10-0
RUN6P_MAX
Run Length 6+ Maximum Limit. Defines the maximum allowable runs of length 6 or more (for both 0 and
1) detected during entropy generation. The number of runs of length 6 or more detected during entropy
generation must be less than RUN6P_MAX, else a retry or error will occur. This register is cleared to the
default POR value by writing the TRNG0_MCTL[RST_DEF] bit to 1.
