Table 102
General format for entering the expert mode and writing coefficients into the TDA9870A
Table 103
Explanation of Table 102
As the coefficients do not fit into one data byte, they have to be split and arranged (see Table 104). The most significant
bit is transferred first.
Table 104
General format (notes 1, 2 and 3)
Notes
1.
2.
3.
X = don’t care.
MST = most significant third.
LST = least significant third.
The general format described in Table 104 shows the minimum number of data bytes required, i.e. two bytes for the
transfer of a single coefficient.
Should more than one coefficient be sent, then the CRAM address will be automatically incremented after each
coefficient, resulting in writing the sequence of coefficients into successive memory locations, starting at
CRAM ADDRESS. A transmission can start with any valid CRAM address. If two coefficients are to be transferred, they
are arranged as shown in Table 105.
Table 105
Transfer of two coefficients
With any odd number of coefficients to be transferred, the least significant nibble of the last byte is regarded as containing
don’t care data.
