Fast-comparison DAC threshold adjust for high TXP. This value is added to the APC DAC value recalled from
Table 06h. If the sum is greater than 0xFF, 0xFF is used. Comparisons greater than VHTXP, compared against
VMON2, create a TXP HI alarm. The same ranging applied to the APC DAC should be used here.

Fast-comparison DAC threshold adjust for low TXP. This value is subtracted from the APC DAC value recalled
from Table 06h. If the difference is less than 0x00, 0x00 is used. Comparisons less than VLTXP, compared
against VMON2, create a TXP LO alarm. The same ranging applied to the APC DAC should be used here.
