- both master and slave mode. Each controller can switch between master and slave
- at run time (i.e. IPMB mode). Each controller has two 16 byte HW FIFO for TX and
- RX.
+ The NPCM7XX includes sixteen I2C bus controllers and the NPCM8XX includes
+ twenty-seven I2C bus controllers. NPCM8XX controllers 24-26 are connected on I2C
+ pins in parallel to controllers 8-10.
