3.4.10 SMB/I2C

The CB1052 can communicate with external devices via the SMBus protocol or the I2C protocol. The

signals for these protocols are available through a 2x5 pin connector (JST B10B-PHDSSLFSN, mating

connector: PHDR-10VS). The SMBus signals are processed by the chipset, the I2C signals are

processed by the SIO unit.
