4.6. Data I/O Ports
4.6.1.
All Data_Out and Data_In signals are directly connected to the respective port (refer to Figure 4-2). The A²SI-
L IC has only two data output pins (DO0 and DO1). Therefore the information bits I3 and I2 of the master call
are not transferred to the A²SI-L data outputs. Since the A²SI-L IC has only two data input pins (DI2 and DI3)
both lower order information bit (I1 and I0) of the slave response are set to “0” if the IC answers a Data
Exchange master telegram.
If the EEPROM flag Invert_Data_In (refer to Table C.1 ) is set, all input data is inverted. This feature will
simplify the circuitry for NPN-inputs.
The data input pins (DI2 and DI3) are sampled in a time frame that starts not earlier as the point in time of the
end bit of the related Data Exchange master call and ends at least at the end of the start bit of the
corresponding
a
4.6.2.
The regular function of the data pins DO0 and DO1 is to send out the corresponding master telegram data of
the call Data Exchange (DEXG, refer to Table 3.5). DO0 corresponds to I0 and DO1 corresponds to I1. In
addition to that the A²SI-L IC performs a PWM function which is dedicated for the brightness control of LEDs
that are interconnected to DO0 and/or D
flag PWM_enable (refer to Table C.1 ).

Low End Device AS-Interface
In extended address mode the "Select Bit" defines whether the A- Slave or B- Slave is being addressed.
The Enter Program Mode master call is intended for factory programming of the IC only. In order to
achieve EEPROM firmware protection and in order to satisfy the AS-interface Complete Specification the
call Enter Program Mode must be deactivated by setting the Program_Mode_Disable flag before shipment
of the slave.
