OMn_1-0
Output Mode of IO Pin n (n=3..0).
Setting corresponding bits drive output pin with different output mode.
Possible modes are:
00: always LOW
01: 0.5 second HIGH/LOW cycle
10: 1 second HIGH/LOW cycle
11: always HIGH
These bits have no effect for input pin.
Note:
The ISDN clock must exist for the output cycle to take effect. If the S/T interface does not have clock input, it is
necessary to enable clock by writing 1 to register CIX.
