Serial Programming Bus
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). Additional leading
bits are ignored and there is no check made how many pulses arrived during enable low
condition. During enable low condition the bus current is increased to speed up the bus
logic.
To keep all information in the registers during standby, DATA_HOLD must be set to high
condition. In this case the power-down current is below 100 μA.
The programming of the transceiver is separated into two data words. Data word 1 con-
trols mainly the channel information together with settings, which are closely related with
the channel. Dataword 2 holds setup information, which is adjusted during production.
