Notes
1.
The gray area indicates it has content but users do not need to understand it. Users only need to configure them according
to the parameters exported from RFPDK. Users need follow the procedure of
read-modify-write
to set an individual bit to 1 or
0.
2.
The blue area indicates that users need to understand it. The registers will be detailed one by one in below.
3.
The built-in packet structure pattern of the CMT2189B is the same as that of the CMT2157B. Users can select the packet
structure of the CMT2157B in RFPDK configuration screen. The configuration parameters generated in
exp
are arranged
according to required format and order. Users only need to fill in the specific data content during software executing.
2.7.1 Tx Rate
The Tx rate is determined by SYMBOL_TIME<15:0> and can be generated by RFPDK.
