Function Mode 2
Mode 2 is triangle modulation type as following.
Frequency modulation is set by serial input resister.
(1) Operation mode
: Resister 1
(2) Frequency modulation period (Trate)
: Resister 2
(3) Frequency modulation start position (Tstart)
: Resister 3
(4) Output center frequency (fcenter)
: Resister 4
(5) Output peak frequency (fpeak)
: Resister 5
(6) 1st.pole position (1stPole)
: Resister 6
(7) 2nd.pole position (2ndPole)
: Resister 7
