These bits are set when moisture detection on SBU using volt-
age source didn’t detect moisture. “01” and “10” will be set with
other register bit such as bit0/1 or bit4/5
00 : No moisture detection tried on SBU
01 : Moisture was detected on CC but not found on SBU
10 : Moisture was detected by SBU Float voltage detec-
tion(SBUFT) but not found on SBU
11 : No moisture detected on both CC and SBU
