Data Sheet
7.3.9
Value after reset: 00
IOM_CR
SPU
0: The DU line is normally used for transmitting data
1: Setting this bit to ’1’ will pull the DU line to low. This will enforce connected layer 1
After a subsequent CIC-interrupt (C/I-code change; ISTA) and reception of the C/I-code
”PU” (Power Up indication in TE-mode) the microcontroller writes an AR or TIM
command as C/I-code in the CIX0-register, resets the SPU bit and wait for the following
CIC-interrupt.
TIC_DIS
0: The last octet of the last IOM time slot (TS 11) is used as TIC bus
1: The TIC bus is disabled. The last octet of the last IOM time slot (TS 11) can be used
EN_BCL
0: The BCL clock is disabled
1: The BCL clock is enabled
CLKM
If the transceiver is disabled (DIS_TR = ’1’) the DCL from the IOM-2 interface is an input.
With
0: A double clock per bit is expected
1: A single clock per bit is expected
DIS_OD
0: IOM outputs are open drain driver
1: IOM outputs are push pull driver
DIS_IOM
DIS_IOM should be set to ’1’ if external devices connected to the IOM interface should
be “disconnected“ e.g. for power saving purposes or for not disturbing the internal IOM
devices to deliver IOM-clocking.
