3.6.7. TX Data Rate Generator
The data rate is configurable between 1–128 kbps. For data rates below 30 kbps the”txdtrtscale” bit in register 70h
should be set to 1. When higher data rates are used this bit should be set to 0.
The TX date rate is determined by the following formula:
The txdr register may be found in the following registers.
