RX23W Group 48. Data Operation Circuit (DOC)
48. Data Operation Circuit (DOC)
48.1 Overview
The data operation circuit (DOC) is used to compare, add, and subtract 16-bit data.
Table 48.1 lists the data operation circuit specifications and Figure 48.1 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.
