Seven lower counter bits count in the beginning of zero semi-period of note. After reaching
the code equal to the contents of 7 lower bits of KT2 register, 7 lower bits of the counter are
cleared but the highest bit is switched into logic 1 and then the note second (unit) semi-
period is counted in the same way.
As a result on output the frequency of 65565Hz/2N is formed, where N is number from 2 to
127, set in 7 lower bits of register KT2. To form notes period with accuracy to one period of
input frequency 65565 Hz the following possibility is forseen. When setting in register KT2
the higher bit of KT register in logic 1 when counting the second (unit) semi-period at code
reaching, equal to the contents of 7 lower bits of register KT2, 1-6 bits of timer are set into 0,
but the lowest bit is set into 1 and, thus, the following zero semi-period of note is "cut" for one
period of input signal. In this case the frequency equal to 65565 Hz / (2N-1) can be formed.
Formed notes frequency (output T2_7) can be supplied on external output "AL" at set into 1
flag AL_EN in the state register R7.
On output "AL" output T2_7 is also applied (at set into 1 flag AL_EN) at the following state of
timers control register RFBO:
RFBO_7 RFBO_6 RFBO_5 RFBO_4 RFBO_3 RFBO_2 RFBO_1 RFBO_0

In this mode T2 is clocked by external signal (RC-oscillator), Т3 by clearing signal Т2 («short»
pulse FrT2) , injection of the signal from output T2_7 on output «AL» is used for testing
(measurement of RC-oscillator frequency).
