-2 Clocks Enable Control
Enables the IEC-Q to write Monitor data on DOUT to the MON1
channel instead of the MON0 channel and to write 6-bit C/I
indications on DOUT into the C/I-channel 1
Enables the normal operations where the IEC-Q addresses only
IOM
Disables the internal 6ms Monitor time-out
Enables the internal 6ms Monitor time-out
Selects pin DOUT to be open drain
Selects pin DOUT to be tristate
Enables the superframe marker function
Disables the superframe marker function
Combined with the SWST:MON = "1" and ADF2:TE1 = "0" bits,
enables the controller to access the core of the IEC-Q
Combined with the SWST:MON = "1" and ADF2:TE1 = "0" bits,
enables the controller to access the IOM
out of the IEC-Q
Inverts meaning of pin ICE.
Clocks are enabled if pin ICE=0. Clocks are disabled if pin ICE=1
The status of pin ICE is valid (Reset value)
