Most of the registers described here would not normally be accessed by the host. They are documented
here mainly for debug purposes. In typical operation, the DEU is used through channel-controlled access,
which means that most reads and writes of DEU registers are directed by the SEC channels. Driver
software would perform host-controlled register accesses only on a few registers for initial configuration
and error handling.
10.7.4.1
The DEU mode register contains 3 bits which are used to program DEU operation.
The mode register is cleared when the DEU is reset or re-initialized. Setting a reserved mode bit generates
a data error. If the mode register is modified during processing, a context error is generated.
