After 16 SCLK clocks have been input with SEN at the low level, SDATA is acquired on the rise of SEN.
Note : SDATA will not be acquired if 15 or fewer cycles were input during the SEN low-level period. If 17 or more
clock cycles are input, the SDATA for the first 16 cycles are acquired, and the SDATA following those 16 cycles
is ignored.
