Table 2-1. Code Option Table of SN8P1700
Notice : The OSG working voltage and the frequency relation table:
The min. working voltage will be affect by the OSG option. It is very important to check this code option.
Turn on the OSG will improve the EMI performance. But the side effect is an increase in the working
voltage.
