Supervisory Signal Cadence Register B (SSCB)
The SSCB register is used to store the cadence information for Energy Detect Block B. Refer to the description
of the “Energy Detect B - Low Threshold Register (EDBLT)” on page 63.
22.18
Low Tone Coefficient Registers 1-7 (LTC1-7)
The seven
LTC
registers are configured as follows:
22.19
High Tone Coefficient Registers 1-7 (HTC1-7)
The seven
HTC
registers are configured as follows:
Each of the seven programmable Tone Generators has a Low and High Tone Coefficient Register used to
program the two tone frequencies. Frequencies for the programmable tone generators can be specified
according to one of three formula’s, depending on what range the coefficient value is in, as shown in Table 14.
