Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
I
This bit specifies whether the interface may operate in Slave mode. If
set, Slave mode is enabled; otherwise, Slave mode is disabled.
I
This bit specifies whether the interface may operate in Master mode. If
set, Master mode is enabled; otherwise, Master mode is disabled and
the interface clock is disabled.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
I
This bit specifies whether the interface is operating normally or in
Loopback mode. If set, the device is put in a test mode loopback
configuration; otherwise, the device operates normally.
