The activated state of the S-interface is directly indicated via pin ACL (Activation LED).
An LED with pre-resistance may directly be connected to this pin and a low level is driven
on ACL as soon as the layer 1 state machine reaches the activated state (see
Figure
Figure 13
By default (ACFG2.ACL=0) the state of layer 1 is indicated at pin ACL. If the automatic
indication of the activated layer 1 is not required, the state on pin ACL can also be
controlled by the host (see
If ACFG2.ACL=1 the LED on pin ACL can be switched on (ACFG2.LED=1) and off
(ACFG2.LED=0) by the host.
