CC1125 has an internal CORDIC core, which can obtain the sampling value of signal amplitude and phase in real time.However, the user manual's description of relevant registers is too simple, so that I have some doubts in using them.
Problem: registers 0x2F84 (ang1-signal Angular after CORDIC [9:8]) and 0x2F85 (ang0-signal Angular after CORDIC [7:0]) store a 10bit phase sampling value.1. Is the sampling value a signed number or an unsigned number? If it is a signed number, is it expressed in the form of binary complement?2. What is the Angle range corresponding to the sampling value, 0°~360° or other Angle range?
