S10MillerEn If set, pulse modulation is applied according to modified miller code.
Note: This bit shall be set only if S10PulseType is set to 1h
5 to 4 S10PulseType Specifies which type of pulse modulation is selected.
0h - no pulse modulation
1h - pulse starts at beginning of bit
2h - pulse starts at beginning of second bit half
3h - pulse starts at beginning of third bit quarter

S10Inv
If set. the output of Symbol0 and Symbol1 is inverted.

S10EnvType
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.
0h - Direct output
1h - Manchester code
2h - Manchester code with subcarrier
3h - BPKSK
4h - RZ return zero, pulse of half bit length at beginning of second half
of bit
5h - RZ return zero, pulse of half bit length at beginning of second half
of bit
6h - RFU
7h - RFU
