f) Example : (Refer to Example 2 diagram)
The following example shows the case when PT2248 Code Bits C1 = 0,
C2 = 0, and C3 = 1. The CODE1 and CODE2 pins of the PT2250A Series
are connected to the Vss (C1=0 and C2=0). In this way, the PT2250A or
any of its series matches the C1 and C2 Code Bits of PT2248; thus, the
remote commands are correctly decoded.
