A-D comparate result flag 1: Analog input voltage < comparison voltage
Note 1: During comparator mode, the bits in this register correspond one for one to channels 0–15.
Note: • This register must always be accessed in halfwords.
When comparator mode is selected using the A-D Single Mode Register 1 ADSMSL (A-D conversion mode
select) bit, the selected analog input voltage is compared with the value written to the A-D Successive Approxi-
mation Register and the result is stored in the corresponding bit of this comparate data register.
The bit or flag in this register is "0" when analog input voltage > comparison voltage, or "1" when analog input
voltage < comparison voltage.
