4-wire Serial Interface
ATA5823/ATA5824
Table 13-1.
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.
Pin CS_POL defines the active level of the CS:
Table 13-2.
When CS is inactive and the transceiver is not in RX transparent mode, SDO_TMDO is in a
high-impedance state.
Pins SCK_POL and SCK_PHA defines the polarity and the phase of the serial clock SCK.
Figure 13-7. Serial Timing SCK_POL = 0, SCK_PHA = 0
