Configuration data

13 Configuration data

STFPC320

To read the configuration data from STFPC320, 0x71 command (Section 7.2: Data setting

command on page 36) is sent from the Host to STFPC320. After this, the STFPC320 will

output a maximum of 14 bytes with the configuration data. The Host can choose to read only

a few bytes by pulsing the SCL line according to the number of bytes to be read.

Up to a maximum of 14-bytes are sent from MSB to LSB as configuration data. The 14-bytes

represent the following configuration information.
