* some notes:
* - writing does not loop; if writing to the end then new writes will cause an error interrupt.
* - added write protection for first 16 bytes.
* - many registers will only commit to action upon valid I2C stop received.
* - the code don't send NACKs on invalid writes.
* - write registers will only commit to action upon valid I2C stop received.
