CMPVALL and the lower 2 bits of CMPVALH specify the voltage to be compared.
CMPVALH and CMPVALL are assigned to the same addresses as ADDR2 (ADDR2_2) and
ADDR3 (ADDR3_2), respectively. CMPVALH and CMPVALL become valid in compare mode.
Table 24.4 shows the correspondence between VAL[9:0] setting and the voltage to be compared.
