The above shows an example of the signal sequence that can set the next operation mode of MBI5170 to be the
Current Adjust Mode. The LE/MOD/CA active pulse here would not latch any serial data.
Writing Configuration Code (In Current Adjust Mode)
In the Current Adjust Mode, by sending the positive pulse of LE/MOD/CA, the content of the Shift Register with a
Configuration Code will be written to the 8-bit Configuration Latch.
Switching to Normal Mode
The above signal sequence example can make MBI5170 resume to the Normal Mode.
Note:
If users want to know the whole process, that is how to enter the Current Adjust Mode, write the Configuration
Code, and resume to the Normal Mode, please refer to the section
