Hi,
I have a question concerning some of the read-only registers of the LMX2820. The registers R71 - R76 and R113 - R122 are defined as read-only, with a default value of 0x00, in the register map.
When I start the LMX2820 and only peform a software reset (by writing R0 = 0x4062, followd by R0 = 0x4060) and read out all register values afterwards, the values of most of the read-only registers are not zero:
For the "non-zero" registers I get: R71 = 0x8801, R72 = 0x08, R73 = 0x9800, R74 = 0x37E1, R75 = 0x032C and R119 = 0x09.
Is this the expected behaviour?
Thank you!
Best regards
Joachim
