9.4.2 Read Functions

The read mode of the interface means that the micro controller reads register value from the driver. To achieve read

function, the micro controller first has to send a command (read ID or register command) and then the following byte is

transmitted in the opposite direction. After that CSX is required to go to high before a new command is send (see the below

figure). The driver samples the SDA (input data) at rising edge of SCL, but shifts SDA (output data) at the falling edge of

SCL. Thus the micro controller is supported to read at the rising edge of SCL.

After the read status command has been sent, the SDA line must be set to tri-state no later than at the falling edge of SCL

of the last bit.

3-line serial protocol (for RDID1/RDID2/RDID3/0Ah/0Bh/0Ch/0Dh/0Eh/0Fh command: 8-bit read):
