11.2. Integer and Fractional Math
MAC0 is capable of interpreting the 16-bit inputs stored in MAC0A and MAC0B as signed integers or as
signed fractional numbers. When the MAC0FM bit (MAC0CF.1) is cleared to ‘0’, the inputs are treated as
16-bit, 2’s complement, integer values. After the operation, the accumulator will contain a 40-bit, 2’s com-
plement, integer value. Figure 11.2 shows how integers are stored in the SFRs.
When the MAC0FM bit is set to ‘1’, the inputs are treated at 16-bit, 2’s complement, fractional values. The
decimal point is located between bits 15 and 14 of the data word. After the operation, the accumulator will
contain a 40-bit, 2’s complement, fractional value, with the decimal point located between bits 31 and 30.
Figure 11.3 shows how fractional numbers are stored in the SFRs.
