(7Eh) Bit rate ENUM
USINT 0 = "1 Mbps"
1 = "500 kbps"
2 = "250 kbps"
3 = "100 kbps"
4 = "125 kbps"
5 = "83 kbps"
6 = "71 kbps"
7 = "62.5 kbps"
8 to 15: reserved

(80h) Frame length G/S USINT Number of bits of the SSI data frame.
FRAME LENGTH must always be greater
than
INVALID_BITS.
A
Default: 25 = 19hex
129
(81h) Kind of coding SSI G/S BOOL 0 = "Binary code"
1 = "GRAY code"
130
(82h) Invalid
bits MSB G/S USINT Number of invalid bits on the MSB side of
the position value supplied by the SSI
encoder. The meaningful word width of the
position value transferred to the module bus
master is as follows:
FRAME LENGTH -
INVALID BITS MSB -
INVALID BITS LSB.
The invalid bits on the MSB side are zeroed
by masking the position value. I
NVALID BITS MSB
+ INVALID BITS LSB must always be less
than FRAME LENGTH.
Default: 0 = 0hex
