Description
Note: Bits are skipped at the end of the byte
Defines how many bits of the first data byte to be sent.
If set to 000b all bits of the last data byte are sent.
Note: Bits are skipped at the beginning of the byte
Defines the number of bytes to be transmit. The maximum
number of bytes is 260 (0x104).
If the Transmission Of Data Is Enabled
(TX_DATA_ENABLE) and TX_NUM_BYTES_2_SEND is
zero, then a NO_DATA_ERROR occurs.
Description
Reserved
Specifies the length of a pulse for sending data with miller
pulse modulation enabled. 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
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.
Direct output
Manchester code
Manchester code with subcarrier
BPSK
RZ (pulse of half bit length at beginning of second half of bit)
RZ (pulse of half bit length at beginning of bit)
Manchester tuple coding
Reserved
Specifies the frequency of the subcarrier.
424 kHz
