1. A read from the data register returns the value of the GPIO module input port. These ports have a
default pin assignment. The read value default is the pin state based on the default pin map.
2. Port E bits 1 and 0 provide the LED driver function. The Port E[1:0] defaults to drive high. A read from
the Port E data register would be expected to return 0x03, if the other pins mapped to Port E inputs are
zero. However since the Port E[7:2] inputs are mapped to IDE control signals, the default read value will
depend on the default action of the IDE controller and the external interface.
3. The RAWSTATUSx registers have pin dependent default read states. The interrupt control registers
default to low level sensitive interrupt on reset. Therefore the external pin state will ripple through the
interrupt logic to determine the RAWSTATUSx default.
