IOM Control Register (IOMC)
The bit rates, the selection of active slots on the IOM interface and the logic connection between an IOM slot and an IOM
data buffer are defined in the IOM Control Register. The IOM modes which can be selected are listed in Table 61.
Writing to the IOMC register is done via the Application Programming Interface (API) software. Please refer to the API
specification for more details.
