Control Bus Enable. Enable pin for the three-
wire serial control bus that sets the operating
frequency and programmable options. The
control registers are loaded on a low-to-high
transition of the signal. Serial control bus data
is ignored when this signal is high. This is a
CMOS input, and the thresholds are
referenced to VDD and VSS.
Serial Control Bus Data. 16-bit words, which
include programming data and the two-bit
address of a control register. This is a CMOS
input, and the thresholds are referenced to
VDD and VSS.
Serial control bus data is clocked in on the
rising edge when EN is low. This is a CMOS
input; the thresholds are referenced to VDD
and VSS.
