7.4.4

Dynamically assigned addresses

The device supports I3C Dynamic Address Assignment, which is initiated by the external host

controller with the broadcast common command code 'Enter Dynamic Address Assignment'

(ENTDAA).

The device supports Dynamic Address Assignment in the condition where the external host

can overwrite the device statically assigned address using the common command code 'Set

Dynamic Address from Static Address' (SETDASA).

After an address is dynamically assigned, the device only responds to the newly assigned

address and no longer responds to the default target address. The dynamically assigned

address shall be used until the device is reset, at which point the device shall return to its

default target address.

7.4.5

Default I²C and I3C slave address

The default 7-bit I²C / I3C address is defined as follows. The ID1 and ID0 are input pins of the

device.

of ID1 and ID0.
