Serial data (SDA) is shifted into the register on the rising edge of
the clock (SCK), least significant bit (LSB) first. The attenuator will
change states on the rising edge of the latch-enable (LE) signal,
according to the most recent 5 bits of shifted data accepted since
the previous falling edge of the LE signal.
Power-up sequence:
0. Connect ground
1. Apply VDD
2. Set all inputs (SCK, SDA, LE)
Power-down sequence should be the reverse of above.
