Overview of anti-spike filter management

The device acts as a standard I²C target as long as it has an I²C static address. The device is capable of

detecting and disabling the I²C anti-spike filter after detecting the broadcast address (7'h7E/W). In order to

guarantee proper behavior of the device, the I3C master must emit the first START, 7'h7E/W at open-drain speed

using I²C fast mode plus reference timing.

After detecting the broadcast address, the device can receive the I3C dynamic address following the I3C push-

pull timing. If the device is not assigned a dynamic address, then the device continues to operate as an I²C device

with no anti-spike filter. For the case in which the host decides to keep the device as I²C with anti-spike filter, there

is a configuration required to keep the anti-spike filter active. This configuration is done by writing the ASF_CTRL

bit to 1 in the IF_CFG (03h) register. This configuration forces the anti-spike filter to always be turned on instead

of being managed by the communication on the bus.
