Description
Reads as one. Indicates that no separate reference clock is
provided.
Reads as one. The calibration value is not exactly 10ms because of
clock frequency. This could affect its suitability as a software real
time clock.
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
An optional Reload value to be used for 10ms (100Hz) timing,
subject to system clock skew errors. The value read is valid only
when core clock is at 48MHz.
