(2) Input clock selection of B.I.T
The input clock of B.I.T can be selected from the prescaler within
a range of 2us to 256us by clock input selection bits
(BTS2~BTS0). (at fex = 4MHz). In reset state, or power on reset,
BTS2=``1``, BTS1=``1``, BTS0=``1`` to secure the longest oscil-
lation stabilization time. B.I.T can generate the wide range of ba-
(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
