PortStateRead: IOType=26

PortStateRead, 1 Command Byte:
0	IOType=26

3 Response Bytes:
0-2	State

This IOType reads the state of all digital I/O, where 0-7=FIO, 8-15=EIO, and 16-19=CIO. Only lines configured as digital (not analog) return valid readings.

State: Each bit of this value corresponds to the specified bit of I/O such that 1=High and 0=Low. If all are low, State=d0. If FIO0-FIO2 are high, EIO0-EIO2 are high, CIO0 are high, and all other I/O are low (b000000010000011100000111), State=d67335.
