Standby Mode Programming

Each F4482 channel can be placed into a standby mode via the dedicated Channel STBY pins (STBY_A, STBY_B, STBY_C, and STBY_D);

for information, see truth table shown in Table 11). Note that when a channel is disabled, the serial register for that channel will hold the last

enabled DSA state.
