Description
SMB_CLK Frequency. This field along with SMBCTL3 defines the SMB_CLK period
(low and high time) when the device serves as a bus master. The clock low and high
times are defined as follows:
t
where t
SCLFRQ can be programmed to values in the range of 00010002 (8

The low and high time are generally equal unless two or more devices are driving the
SCL line.
