Data Sheet
7.2.9
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
devices to deliver IOM-clocking.
