1) If Master Key = 6 then test mode write commands are ignored
2) If Master Key < > 6 or 9 then extended function mode is disabled
3.10 Modulator
The modulator consists of data encoders for the following basic types of modulation:

Direct Data Output
FSK/8-/5
0 = RF/8;
FSK/8-/10
0 = RF/8;
FSK/5-/8
0 = RF/5;
FSK/10-/8
0 = RF/10;
Phase change when input changes
Phase change on bit clock if input high
Phase change on rising edge of input
0 = falling edge, 1 = rising edge
1 creates an additional mid-bit change
1 = damping on, 0 = damping off
1 = RF/5
1 = RF/10
1 = RF/8
1 = RF/8
Notes: 1. A common multiple of bit rate and FSK frequencies is recommended.
2. In PSK mode the selected data rate has to be an integer multiple of the PSK sub-carrier
frequency.
