T2802
With bits E6 - E10
Only in TX mode effective. Used to control the power of the external PA by adjusting the
ramping voltage.
With bits E3 - E5
Only in TX mode effective. Adjusts the modulation compensation circuit for closed-loop
modulation. This adjustment is done with a test sequence of a long stream of ,1‘ - ,0‘.
The correct setting is achieved if the modulation is not affected by the PLL.
With bits E0 - E2
In normal operation Lock detect output is used. All other settings are for test only.
