Function
Disable Super Frame Marker
’1’ = Inhibits the evaluation of the super frame
marker on FSC. I.e the transmitted super-
frame is not affected by an FSC pulse shorter
than 2 DCL clock periods.
’0’ = The position of the transmitted
superframe is synchronized to short FSC
pulses.
Push Pull Mode
in push pull mode ’0’ and ’1’ is actively driven
during an occupied time slot, outside the
active time slots DOUT is high impedance
(tristate)
’1’= configures DOUT as push/pull output
’0’= configures DOUT as open drain output
CRC Check On/Off
defines the condition on which MON-2
messages and M4 bit will be passed on,
the setting has effect on all ports (see
Table
Pin CRCON is evaluated only after hardware
reset.
’1’= CRC Check On
MON-2 messages are not issued and M4-bit
are not forwarded to the statemachine if the
CRC-check of the U-superframe containing
M4-bit changes is not ok.
(MFILT= 0011 0xxx)
’0’= CRC Check Off
MON-2 messages are issued every time a
change in at least one of the overhead bits
(M4,5,6) of the U-interface is detected,
regardless of the CRC checksum status.
M4-bit are forwarded to the statemachine with
triple-last-look filtering (TLL).
(MFILT= 0000 0xxx)
reserved, clamp to high
