RxStopOn
InvPar
If set to 1, inverse parity bit is a stop condition
4
RxStop
OnLength
If set to 1, data reception stops when the number of received bytes
reach the defined frame length. The value for the frame length is taken
from the first data-byte received.
3
RxMSBFirst
If set to 1, data bytes are interpreted MSB first for data reception,
which means data is converted at the CLCoPro interface. If this bit is
set to 0, data is interpreted LSB first
2
RxStopBitEn
Set to 1, a stop-bit is expected and will be checked and extracted from
data stream. Additionally on detection of a stop-bit a reset signal for
the demodulator is generator to enable a re-synchronization of the
demodulator. If the expected stop-bit is incorrect, a frame error flag is
set and the reception is aborted.
Note: A stop bit is always considered to be a logic 1
1
RxParityType
Defines which type of the parity-bit is calculated.
0b:……………..Even parity
1b:……………..Odd parity

Description
7 to 0
RxEOF
Symbol
This value defines the pattern of the EOF symbol with a maximum
length of 4 bit. Every tuple of 2 bits of the RxEOFSymbol encodes one
bit of the EOF symbol. A 00 tuple closes the symbol. In this way
symbols with less than 4 bits can be defined, starting with the bit0 and
bit1. The leftmost active symbol pattern is processed first, which
means the pattern is expected first. If the bit0 and bit1 are both zero,
the EOF symbol is disabled. The following mapping is defined:
00b - no symbol bit
01b - zero value
10b - one value
11b - collision
Example:
00011101b (1Dh): Zero-Collision-Zero
11101000b (E8h): No symbol because two LSBits are 0
