// get a 10 bit I2C address.
// Comm (8 bits): Command byte, a data byte which often selects a register on

// Data (8 bits): A plain data byte. Sometimes, I write DataLow, DataHigh
// for 16 bit data.
// Count (8 bits): A data byte containing the length of a block operation.
// [..]: Data sent by I2C device, as opposed to data sent by the host adapter.
