1 = The last answer to a long message was damaged.
0 = No error detected in the last answer to a long message.
Bit 3 FIX0: This bit always gives a "0". For SPI interfaces, this is used for checking the
spi_miso pin for stuck-at-'1' faults.
Bit 2 QMLW: Quality monitoring at Low level (see chapter 6.3.3)
1 = Current value of quality monitoring less than 14.
0 = Current value of quality monitoring greater than or equal to 14.
Bit 1 FREL: Channel status for “long message”.
1 = The channel for the “long message” is free.
0 = The channel for the “long message” is in use.
Bit 0 FRES: Channel status for the "short message". 1 = The channel for the "short message"
is free.
0 = The channel for the "short message" is in use.
6.3 DSL Master function register
The protocol logic controls the performance of the DSL Master via the registers in the
DSL Master IP Core on drive interface. These registers are also used for accessing the
position values.
The table below contains a list of all the function registers available in the IP Core.
NOTE
The addresses given below are referencing a big-endian addressing. For a table stating
the register addresses depending on the endianness, see chapter 9.5.
