T8/T16 Control Register A (CTR1)
The T8/T16 Control Register A controls the functions in common with both the T
and T
operation: Transmit Mode and Demodulation Mode. Transmit Mode is used for
generating complex waveforms. The Transmit Mode has two submodes: Normal
Mode and Ping-Pong Mode. The settings for CTR1 in Transmit Mode are given in
Table 37.
