=== I2C Controller ===
14
15
The controller has two oddities:
16
 * It assumes that the peripheral has an address byte.  If your peripheral doesn't, you have to
17
   write the first byte into the address register and not the FIFO
18
 * You cannot under-fill the FIFO, i.e. if you write 8 bytes into the 16byte deep fifo, the controller
19
   will transmit 16 bytes rather than 8.  Therefore, always limit the FIFO depth to your write size!
