Table 36. Command Structure
The 4-wire serial interface consists of the Chip Select (CS), the Serial ClocK (SCK), the
Serial Data Input (SDI_TMDI) and the Serial Data Output (SDO_TMDO). Data is trans-
mitted/received bit by bit in synchronization with the serial clock.
Note:
When CS is low and the transparent mode is inactive (T_MODE = 0), SDO_TMDO is in
a high-impedance state. When CS is low and the transparent mode is active
(T_MODE = 1), the RX data stream is available on pin SDO_TMDO.
