* There are several parameters in many of the commands that bear further
* explanations:
*
- * Two of the commands (imm and imw) take a byte/word/long modifier
- * (e.g. imm.w specifies the word-length modifier). This was done to
- * allow manipulating word-length registers. It was not done on any other
- * commands because it was not deemed useful.
- *
* {i2c_chip} is the I2C chip address (the first byte sent on the bus).
* Each I2C chip on the bus has a unique address. On the I2C data bus,
* the address is the upper seven bits and the LSB is the "read/write"
