This IOType writes the direction of all digital I/O, where 0-7=FIO, 8-15=EIO, and 16-19=CIO. Note that CIO0-2 and MIO0-2 are shared, so for writes to MIO0-2 use channel numbers 16-18.
- WriteMask: Each bit specifies whether to update the corresponding bit of I/O.
- Direction: Each bit of this value corresponds to the specified bit of I/O such that 1=Output and 0=Input. To configure all as input, Direction=d0. For all 20 standard digital I/O as output, Direction=d1048575. To configure FIO0-FIO2 as output, EIO0-EIO2 as output, CIO0 as output, and all other I/O as input (b00010000011100000111), Direction=d67335.
