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
enables/disables SSP test mode
’1’= SSP test mode enabled,
+1 pulses are issued at the four line ports in
1ms intervals
’0’= SSP test mode disabled
This pin function corresponds to the SW
selection by C/I= SSP besides the fact that the
HW selection impacts all line ports while the
SW selection impacts only the chosen line
Note: For activation of SSP test mode, pin
Data Through (DT) Test Mode
enables/disables DT test mode
’1’= DT test mode enabled,
the U-transceiver is forced on all line ports to
enter the ’Transparent’ state
’0’= DT test mode disabled
This pin function corresponds to the SW
selection by C/I= DT besides the fact that the
HW selection impacts all line ports while the
SW selection impacts only the chosen line
Note: For activation of DT test mode, pin RES
