Preliminary Information

Serial Programming Bus
The transceiver is programmed by the 3-wire bus
(CLOCK, DATA and ENABLE).
After 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. After
enable returning to high condition the programmed
information is loaded into the addressed latches,
according to the addressbit 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.
The programming of the transceiver is separated into two
data words. Data word 1 controls mainly the channel in-
formation together with settings, which are closely
related with the channel. Dataword 2 holds setup informa-
tion, which is adjusted during production.
