MWPS Micro Wire Port Select register (Signifi-
cant in microwiremode only).
(write only)
Default value: Mode A (5410 compatible)
– Writting FFH value select the mode B to ex-
changedata ontoCI & CO
– Writing 00H value select the mode A (See Mi-
crowire control interface paragraph for more
detailsMode A, Mode B).
Note: Soft Reset has no effect on the select
mode.
BAUD DELAY Register (DBAUD)
After reset:00H
DBAUD7 DBAUD6 DBAUD5 DBAUD4 DBAUD3 DBAUD2 DBAUD1 DBAUD0
8 bits read-only register that provides the round
trip bauds delay (12.5usecstep). It is significantin
LT modeonly. The register is split in two sections:
DBAUD4..DBAUD0: 5 bits counterof bauds delay
between SFSx and SFSr rising edges (
total digi-
tal delay: tdd
).
DBAUD7..DBAUD5: 3 bits to store the internal
elastic memory (FIFO) state. The table A shows
the coding of the 3-stages elastic memory (
elas-
tic digital delay:edd
).
Table A.

-2: 2 bauds have to be subtracted from bauds

0: no correction
All other FIFO states are used during activation
procedure. Once PLL2 is frozen you can be only
in one of the 3 statesin tableA.

8bits read-only register that provides the phase
difference between transmit clock and receive re-
covered clock by PLL2 in steps of 65.1 nsec.
(
clock elastic delay: ced
). The register is signifi-
cant in LT mode only.
