Enhanced_Status_Indication

If set, Enhanced Status Indication Mode

according to the AS-Interface Complete

Specification is activated.

Activates LED2 output! For compatibility to

A²SI board layouts, this flag must not be

set (= 0).

Dual_LED_Mode

If set, LED1 and LED2 output signals are

controlled to comply with the dual LED

indication configurations of AS-i. Generated

signals also depend on the value of the

Enhanced_Status_Indication flag. Direct

connection of a dual LED is supported.

Activates LED2 output! For compatibility to

A²SI board layouts, this flag must not be

set (= 0).

FID_Invert

The FID input value is inverted before further

processing.

Safety_Mode

If set, the ASI4U/ASI4U-E/ASI4U-F Safety

Mode is enabled and a special data input

routing is activated.

Synchronous_Data_IO

Enables Synchronized Data I/O Mode

P2_Sync_Data_IO_Activation

If flag is set, the logic value at the parameter

pin P2 determines whether the Synchronous

Data IO Mode is active or inactive.

If flag is not set, the Synchronous Data IO

Mode is always active if it was enabled by the

Synchronous_Data_IO flag.

Ext_Addr_4I/4O_Mode

Enables 4 Input / 4 Output support in

Extended Address Mode.

ID_Code1_Protect

If flag is set, ID_Code_Extension_1 is write-

protected for user access.

In Extended Address Mode, only bits 2 to 0

are blocked. Bit 3 is used for A/B slave

selection and must remain user accessible.

0 to 3

ID1_Bit0 to ID1_Bit3

Protected_ID_Code_Extension_1

If the ID_Code1_Protect flag is set, a

Read_ID_Code_1 request will be answered

with the data stored in this register.

0 to 3

Trim Area; accessible by IDT only

0 to 3
