FIGURE 4: FUNCTION SELECT (DB28 - DB31). After the data in FREQUENCY/CHANNEL (DB0 - DB23)
is multiplied by 10
n where the value of n is determined by the contents of MULTIPLIER (Figure 3), it is then
routed internally to the START, STOP, STEP, REF or CHANNEL registers based on the contents of FUNC-
TION SELECT as shown below.
