Digital in/out and poll commands are sent as one byte:
+-+-+-+-+-+-+-+-+
|0|0 0| chan | Bit clear
+-+-+-+-+-+-+-+-+
+-+-+-+-+-+-+-+-+
|0|0 1| chan | Bit set
+-+-+-+-+-+-+-+-+
+-+-+-+-+-+-+-+-+
|0|1 0| chan | Bit get
+-+-+-+-+-+-+-+-+
+-+-+-+-+-+-+-+-+
|0|1 1| chan | Channel get
+-+-+-+-+-+-+-+-+
Channels are sent as 2 to 6 bytes, depending on resolution:
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
2 |1| bit8...bit2 | |0|bit| chan |
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
3 |1|bit15...bit9 | |1| bit8...bit2 | |0|bit| chan |
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
...
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
6 |1|bit31...bit30| |1|bit29...bit23| ... |0|bit| chan |
+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+
Channel 31 is special, as it serves as the configuration channel. When
reading from it multiple responses are sent with the following layout
+-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-+
| command specific data |cmd|kind |conf chan|
+-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-+
kind: 000 == end of configuration
001 == digital in
010 == digital out
011 == analog in
100 == analog out
101 == counter in

+-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-+
