4.1.4.3 Reading Basic Interval Timer
By reading of the Basic Interval Timer Register(BITR), we can read counter value of
B.I.T. Because B.I.T can be cleared or read, the spending time up to maximum 65.5ms
can be available. B.I.T is read-only register. If B.I.T register is written, then CKCTLR
register with same address is written.
