3.8.1
The AUX interface provides various functions, which depend on the operation mode (TE,
LT-T, LT-S, NT or Intelligent NT mode) selected by pins MODE0 and MODE1/EAW (see
Table
by the host.

These pins can be used as programmable I/O lines.
As inputs (AOE.OEx=1) the state at the pin is latched in when the host performes read
operation to register ARX.
As outputs (AOE.OEx=0) the value in register ATX is driven on the pins with a minimum
delay after the write operation to this register is performed. They can be configured as
open drain (ACFG1.ODx=0) or push/pull outputs (ACFG1.ODx=1). The status (’1’ or ’0’)
at output pins can be read back from register ARX, which may be different from the ATX
value, e.g. if another device drives a different level.
FBOUT
AUX5 is multiplexed with the selectable FSC/BCL output FBOUT, i.e. the host can select
either standard I/O characteristic (ACFG2.A5SEL=0, default) or FBOUT functionality
(ACFG2.A5SEL=1). FBOUT provides either an FSC (ACFG2.FBS=0, default) or BCL
signal (ACFG2.FBS=1) which are derived from the DCL clock (also see
Data Sheet
15). After reset the pins are switched as inputs until further configuration is done
