0xFFFF Range 0 to 65535
Init
Init
0x1B Range 5 to 128
0x0 Enables demapping for this PHY when 0x1.
0x0 Disables descrambling when 0x1.
0x7 Range 1 to 15
0x6 Range 1 to 15
0x0 One second performance monitoring mechanism is enabled when
0x4 Loss of Cell Delineation (LCD) integration time in ms.
0x0 Range 0 to 255
0x0 0x0 = SIZE_64
0x1, otherwise clear-on-read performance monitoring mechanism is
enabled.
Applies to both ATM and PPP modes.
Applies to ATM mode only.
The minimum number of free words which has to be available in the
FIFO before the POS/ATM Demapper starts writing data to that FIFO.
This value must always be larger than 4.
Applies to PPP mode only, for ATM mode this must always be set to
27 (0x1B).
Minimum Frame Length.
Applies to PPP (no transparent) mode only.
Maximum Frame Length.
Applies to PPP (no transparent) mode only.
0x1 = SIZE_128
0x2 = SIZE_256
0x3 = SIZE_1024
Size of each fixed-length POS-PHY packet (in bytes).
Applies to PPP (transparent) mode only.
Applies to both ATM and PPP mode.
Applies to both ATM and PPP mode.
Note for ATM it is mandatory to enable descrambling in normal
operation.
Threshold for leaving SYNC-state. Its value must be set to a value
different from 0.
Applies to ATM mode only.
Threshold for entering SYNC-state. Its value must be set to a value
different from 0.
Applies to ATM mode only.
