Init
0x55 HEC offset (coset) pattern.
0x0 Enables mapping for this PHY when 0x1.
0x0 Disables scrambling when 0x1.
0x0 Enables insertion of calculated HEC for ATM layer cells when 0x1.
0x0 Enables insertion of calculated HEC for inserted cells when 0x1. Use the
0x0 HEC corruption mask: The HEC is EXORed with this mask. Set to default
0x0 0x0 = NO_MANIP
0x0 The GFC and the VPI field of a UNI cell or the VPI field of a NNI cell for cell
Init
0x1B Range 1 to 128
Applies to both ATM and PPP mode.
Applies to both ATM and PPP mode.
Note for ATM it is mandatory to enable scrambling in normal operation.
Applies to ATM mode only.

Applies to ATM mode only.
0x1 = XOR_HEC
0x2 = AND_HEC
0x3 = OR_HEC
HEC / UDF1 manipulation. Set to the default value for normal operation.

insertion.
Applies to ATM mode only.
0x0 One second performance monitoring mechanism is enabled when
0x1, otherwise clear-on-read performance monitoring mechanism is
enabled.
Applies to both ATM and PPP mode.
The minimum number of words which has to be available in the FIFO
before the POS/ATM Mapper starts to read data from that FIFO. This
value must always be larger than 0.
Applies to PPP mode only, for ATM mode this must always be set to
27 (0x1B).
