5. CUSTOM CODE
SC50462 has a total of 8 bits custom code (C0~C7). Custom Code Bits –C4 and C5 can be externally selected
using the C4 and C5 Terminals. The C4 and C5 pins are inversed; therefore, if the C4 and C5 terminals are
pulled HIGH, then the Custom Code Bits—C4 and C5 would have the Value(0,0). Likewise, when pulled LOW, then
C4 and C5 bits will be (1,1),The other Customs Code Bits,namely:C0~C3 and C6,C7 are fixed at (1,1,1,0) and
(1,0 ):
The waveform of bits are given below:
0.25/0.26ms
Bit "0"
1.00/1.05ms
Bit "1"
2.00/2.10ms
Note: Oscillator Frequency=480 or 455kHz
