CUnet Family MKY44-IO32A
The DIO mode of the MKY44-IO32A occupies the MB (Memory Block) of the SA value that is set by SA0 to SA5 of the ST44SW.
The status of the general-purpose I/O pins (Io00 to Io07, Io10 to Io17, Io20 to Io27, Io30 to Io 37) is stored in bits 0 to 31 of the MB
occupied by the DIO mode of the MKY44-IO32A. Among the statuses of the general-purpose I/O pins stored in bits 0 to 31, the

Selecting the Output Data to the Output Pins in DIO Mode
In the DIO mode of the MKY44-IO32A, the data of the lower or upper 32 bits in the MB (Memory Block) for the DOSA value set by
DOSA0 to DOSA5 of the ST44SW is selected as the data to output. The selection of lower or upper 32 bits is based on the DOHL
setting.
