Data Sheet
The clock pulses will be enabled again when the DU line is pulled low (bit SPU in the
IOM_CR register) i.e. the C/I command TIM = "0000" is received by layer 1, or when a
non-zero level on the line interface is detected. The clocks are turned on after
approximately 0.2 to 4 ms depending on the capacitances on XTAL 1/2.
DCL is activated such that its first rising edge occurs with the beginning of the bit
following the C/I (C/I0) channel.
After the clocks have been enabled this is indicated by the PU code in the C/I channel
and by a CIC interrupt. The DU line may be released by resetting the Software Power
Up bit IOM_CR =’0’ and the C/I code written to CIX0 before (e.g. TIM or AR8) is output
on DU.
The SCOUT supplies IOM timing signals as long as there is no DIU command in the C/
I (C/I0) channel. If timing signals are no longer required and activation is not yet
requested, this is indicated by programming DIU in the CIX0 register.
