... They are controlled by a MCU in the serial mode or the parallel mode (for the HT9200B only). Serial Mode (HT9200A/B) The HT9200A/B employ a data input, a 5-bit code, and a synchronous clock to transmit a DTMF signal. Every digit of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data. Of the 5 Table 1: Digits vs ...
