14.2 Description of READ cycle
1. (start) SEN is LOW or is changed to LOW, i.e., 3-wire interface is
2. (SCLK edge 1 through 7) 7 address bits are clocked in, LSB first.
The fully static CMOS design uses virtually no current when the bus is inactive. It can always capture new data even during power-down. The
data remains latched during power-down (sleep mode).

edges of SCLK (so bits can be accepted by the baseband IC
with the following rising edge).
