(4) Oscillation frequency regulation of Clock IC
1. Oscillation frequency regulation
2. Calculation of regulation value
%Oscillation frequency: INTRB(32KOUT)Measure value,

* example
(1) Oscillation frequency = 32.77076KHz ; Standard frequency = 32.76805KHz
regulation value = (32770.76 - 32768.05)

10+1 = 28.1 28(1C:Hex)
(2) Oscillation frequency = 32.76395KHz ; Standard frequency = 32.76805KHz
regulation value = (32763.95 - 32768.05)

10+1 = -41.015 -41
* The clock frequency output from of the INTRB(32KHz) pin does not change to after the regulation due to
clock regulation circuit.
