C3 = 0. ) In this way, the PT2249A Series can match the C2, C3 Code Bits
of PT2248 and correctly decode the remote commands.

2. Combination of PT2248/PT2250A Series Code Bits
a) PT2250A Series Code Bit C3 is internally pulled high and thereby set at
a default value of “1”. Thus, PT2248 Code Bit C3 must be set at “1”.
b) PT2250A Series Code Bits C2 and C3 may be programmed as follows:
1) “0”, “0” (This combination is not available with TC9150.)
2) “0”, “1”
3) “1”, “0”
4) “1”, “1”
c) To set Code Bit to “1” on PT2248, diodes must be connected to Code
Terminal from the T1 ~ T3 terminals.
d) To set Code Bit to “0” on PT2248, the terminals must be kept floating.
