HP_CODE_RATE
TPS Registers
When this register is written, these bits store the next
Viterbi Code Rate for the Low-Priority stream value that
the system uses. The values are:
The initial condition for the LP_CODE_RATE is 0b000
(1/2).
Viterbi High-Priority Code Rate
When this register is read, these bits provide the last
value received by the channel, using the TPS signalling
information.
When this register is written, these bits store the next
Viterbi Code Rate for the High-Priority stream value that
the system uses. The values are:
The initial condition for these bits is 0b001 (2/3).
