If set to 1, the output envelope is inverted.
Specifies the type of envelope used for transmission of data
packets. The selected envelope type is applied to the
pseudo bit stream.

Description
Reserved
Specifies the length of a pulse for sending data of symbol
2/3. The length is given by the number of carrier clocks + 1.
Reserved
If set to 1, pulse modulation is applied according to modified
miller coding.
Note: Modified miller coding may be used for direct
envelope output (TX_S23_ENV_TYPE ==0)
If set to 1, the output envelope is inverted.
Specifies the type of envelope used for transmission of data
packets. The selected envelope type is applied to the
pseudo bit stream.
