1) If Master Key = 6 and bit 15 set, then test-mode access is disabled and extended mode is active

2) If Master Key = 9 and bit 15 set, then extended mode is enabled

4.10 Modulator

The modulator consists of data encoders for the following basic types of modulation:

“0” = RF/8;

“0” = RF/5;

“0” = RF/10;

“1” = RF/5

“1” = RF/10

“1” = RF/8

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

NRZ

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.
