Bit 0 ~ Bit 7(T20 ~ T27) : Tone generator 2 ‘s frequency divider and power control
Please Run in Normal mode .
Clock source = 111957Hz
T27~T20 = ‘11111111’ => Tone generator2 will has 438Hz SIN wave output.
:
T27~T20 = ‘00000010’ => Tone generator2 will has 55921Hz SIN wave output.
T27~T20 = ‘00000001’ => DC bias voltage output
T27~T20 = ‘00000000’ => Power off
Built-in tone generators can generate dialing tone signals for telephone of dialing tone type or just a single
tone. In DTMF application, there are two kinds of tone. One is the group of row frequency (TONE1), the
other is the group of column frequency (TONE2), each group has 4 kinds of frequency, user can get 16
kinds of DTMF frequency totally. Tone generator contains a row frequency sine wave generator for
generating the DTMF signal which selected by IOCD PAGE0, IOCE PAGE0 and a column frequency sine
wave generator for generating the DTMF signal which selected by IOCA PAGE0. This block can generate
single tone by filling one of these two register.
