This bit cannot be written when the START bit is logic 1.
It is a mandatory condition for card slots 2 to 5 that only one card slot I/O line is enabled at a time. When
switching from one slot to another, the enabled I/O must be disabled before the I/O line for the required card
slot is enabled.
Remark: If both pins I/OUC1 and I/OUC2 are connected at the same time, this mandatory condition also
applies to card slot 1.
In synchronous mode, this bit cannot be written when START bit is logic 1.
