IOM®-2 Clocks Enable
In IOM®-2 Master modes:
’0’: no FSC and DCL clocks are output.
Clocks may be applied to pins FSC and
DCL. However, they are ignored by the
IEC-Q. Data on pin DIN is ignored. Pin
DOUT is ’floating’.
’1’: Behavior as in former versions of
the IEC-Q. The IOM®-2 clocks FSC
and DCL are output on the
corresponding pins.
Due to an internal 100 kOhm pull-up
resistor this is the default configuration
after reset if pin ICE is not connected.
This pin can be overridden by the bit
ADF2:ICEC. For more information
see "IOM®-2 Enable/Disable Mode",
page 53.
In IOM®-2 Slave modes:
Connect to VDD or leave open.
Internal pull up.

Stop/Go Bit Status Pin
available
Gives the status of the S/G bit in TE
mode if the S/G bit control function is
being used, see "Indication of S/G Bit
Status on Pin SG", page 205, for
details.
In all other modes the SG pin in set to
’1’.
