This register is used for data input/output of KPY[7:0]. Every data I/O
is masked with the associated MASK register.
If one of the I/Os is defined as output (see
this register are masked with MASK and then applied to the associated
pin.
If one of the I/Os is defined as input (see
this register hold the masked input value of the associated pin.
