Description
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
Indicates whether the value of TENMS is precise. This
can affect the suitability of SysTick as a software real time
clock.
Indicates whether a separate reference clock is available.
This value is factory preset.
