Overview

The data operation circuit (DOC) is used to compare, add, and subtract 16-bit data.
Table 29.1 lists the data operation circuit specifications and Figure 29.1 shows a block diagram of the data operation
circuit.
16-bit data is compared and an interrupt can be generated when a selected condition applies.
