DC_FEED = 0: The DC feeding coefficient in the Coe-RAM is selected.
DC_FEED = 1: The DC feeding coefficient in the ROM is selected (default);
When the DC feeding is operating at the constant current zone, the FEED_I bit is set to
1, otherwise it is set to 0.
When the DC feeding is operating at the resistive zone, the FEED_R bit is set to 1,
otherwise it is set to 0.
When the DC feeding is operating at the constant voltage zone, the FEED_V bit is set to
1, otherwise it is set to 0.
