S32MillerEn
If set to 1, pulse modulation is applied according to modified miller
code.
Note: This bit shall be set only if S32PulseType is set to 01
5 to 4
S32PulseType Specifies which type of pulse modulation is selected.
00b: no pulse modulation
01b: pulse starts at beginning of bit
10b: pulse starts at beginning of second bit half
11b: pulse starts at beginning of third bit quarter
3
S32Inv
If set to 1, the output envelope is inverted
2 to 0
S32EnvType
Specifies the type of envelope used for transmission of symbol 0 and
symbol 1. The pseudo bit stream is logically combined with the
selected envelope type.
000b: Direct output
001b: Manchester code
010b: Manchester code with subcarrier
011b: BPSK
100b: RZ (pulse of half bit length at beginning of second half of bit)
101b: RZ pulse of half bit length at beginning of bit)
