15:0 | ic_ss_scl_lcnt | This register must be set before any I2C bus transaction can take place to ensure proper I/O timing. This field sets the SCL clock low period count for standard speed. This register can be written only when the I2C interface is disabled which corresponds to the Enable Register register being set to 0. Writes at other times have no effect. The minimum valid value is 8; hardware prevents values less than this from being written, and if attempted, results in 8 being set. |
