Preliminary specification
Terrestrial Digital Sound Decoder (TDSD3)
SAA7283
OVW
This bit is set when new additional data bits are written to
the I
2
C-bus without the previous bits being read.
SAD
This bit is set HIGH when new additional data is written
into the I
2
C-bus, and cleared by the action of reading the
data.
CI1
AND
CI2
These are the CI bits decoded by majority logic from the
parity checks of the last ten samples in a frame.
AD10, AD9
AND
AD8
These are the three most significant additional data bits.
C1, C2
AND
C3
These are the transmitted control bits, see Table 13.
BG/I
When set HIGH this bit indicates that the DQPSK
demodulator is switched to system BGH. When LOW,
indicates that DQPSK demodulator is switched to
system I.
Indicator bits
Table 13 is the truth table for the indicator bits.
