Holds the calculated index based on the MON4 voltage measurement. This index is used for the address during
lookup of Table 06h. M4DAC LUT is 32 bytes from address 80h to 9Fh. The calculation of VINDEX is as follows:
VINDEX
=
MON4
800h
+ 80h
When configured as a single LUT, all 32 bytes are used for lookup.
When configured as a double LUT, the first 16 bytes (80h to 8Fh) form the lower LUT and the last 16 bytes (90h to
9Fh) form the upper LUT.
For the three different modes, the index used during the lookup function of Table 06h is as follows:
