1.6 REGISTERS MAPPING
1.6.1 Control Registers
The control bits mapping is given by the following table:
Table 2
: Control register description
Example:
Register " Reception Control ": MSB LSB
01000011
bit [7:6] "01": identification of the Register " Reception Control "
bit [5:4] "00": set to ’0’
bit [3:2] "00": speed 106K
bit 1
’1’ : automatic speed detection
bit 0
’1’ : external valid
“Address
