16.4.1. SMBus Configuration Register
The SMBus Configuration register (SMB0CF) is used to enable the SMBus Master and/or Slave modes, select the
SMBus clock source, and select the SMBus timing and timeout options. When the ENSMB bit is set, the SMBus is
enabled for all master and slave events. Slave events may be disabled by setting the INH bit. With slave events inhib
