Table 8-1.
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 transmitted/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.
