Modulation compensation circuit Reference counter Typical current consumption 3 Serial Programming Bus T2802 16 TX Mode 58 mA The transceiver is programmed by the 3-wire bus (CLOCK, DATA and ENABLE). After the setting enable signal to low condition on the rising edge of the clock signal, the data is transferred bit by bit into the shift register, starting with the MSB-bit. When the enable signal has returned to high condition, the programmed information is loaded into the addressed latches according to the address bit condition (last bit) ...
