ic_en Status. This bit always reflects the value driven on the
output port ic_en. When read as 1, the controller is deemed
to be in an enabled state.
0x0
When read as 0, the controller is deemed completely inac-
tive.
NOTE: The CPU can safely read this bit anytime. When this
bit is read as 0, the CPU can safely read
SLV_RX_DATA_LOST (bit 2) and
SLV_DISABLED_WHILE_BUSY (bit 1).

IC_FS_SPKLEN
This register must be set before any I2C bus transaction can
take place to ensure stable operation. This register sets the
duration, measured in ic_clk cycles, of the longest spike in
the SCL or SDA lines that will be filtered out by the spike
suppression logic. This register can be written only when the
I2C interface is disabled which corresponds to the
IC_ENABLE register being set to 0. Writes at other times
have no effect. The minimum valid value is 2; hardware pre-
vents values less than this being written, and if attempted
results in 2 being set.
